<p style="text-align: left;">So far we've only talked about dc signals in circuit analysis. These constant signals do not change in time. However, signals must change with time to carry information. The series of videos will cover three basic, time-varying signals used in linear circuits as well as being used to create more complex signal.</p>

<p style="text-align: left;"></p>
<p style="text-align: left;">An electrical signal such as a current i(t) and voltage v(t) is a function of time called a waveform. So far, most of the circuit analysis has been associated with constant or dc waveforms.</p>
<p style="text-align: left;">Upper case letters are used for dc waveforms, e.g. <strong>Vo</strong> or <strong>Io</strong>, and lower case letters are for time-varying signals, like <strong>v(t)</strong> and <strong>i(t)</strong>. However, it is implicit that the lower-case notation for variables <strong>v</strong> and <strong>i</strong> are functions of time or simply waveforms.</p>

Here is a short introduction to active filters and its applications. Active filters have comparable frequency selective performance when compared to passive filters. Active filters require power since operational amplifiers are involved to provide gain but do not require inductors since they can be large and lossy, especially for low frequency applications.<br />

<br />
Briefly, let's begin the talk about the electric filter invented during World War I. These filters and vacuum tubes triggered the growth of telephone and radio communications during the 1920s and 1930s.<br />
<br />
With the dawning of integrated circuits in the 1960, the OP AMP allowed combining filtering and amplification functions now called active filters. Here, in these series of videos, we'll show you how to design a wide range of analog filters.<br />
<br />
These filters can be applied in instrumentation systems audio systems, communication systems, and even digital systems<br />
<br />
So what is an active filter? To put it simply, it's a signal processor that amplifies, attenuates or reshapes the frequency content of input signals.<br />
<br />
There's a whole variety of applications for these filters.<br />
<br />
In communications systems, use filters to suppress noise, to isolate a single communication from many channels, to prevent spillover of adjacent bands, and to recover the original message signal from modulated signals.<br />
<br />
In instrumentation systems, engineers use filters to select a desired frequency components or eliminate undesired ones. In addition, we can use these filters to limit the bandwidth of analog signals before converting them to digital signals. You also need these filters to convert the digital signals back to analog representations.<br />
<br />
In audio systems, engineers use filters in crossover networks to send different frequencies to different speakers. In the music industry, record and playback applications require fine control of frequency components.<br />
<br />
In biomedical systems, filters are used to interface physiological sensors with data logging and diagnostic equipment.<br />
<br />
We recall that passive filters contain only resistors, capacitors and inductors. Although these circuits can be highly selective when losses are low, the response is highly resonant. But they cannot provide passband gains greater than one. In addition, they suffer from loading effects which makes the chain rule in cascade design inapplicable.<br />
<br />
Here, we will emphasize an active filter as a circuit that contains only resistors, capacitors,<br />
and OP AMPS.<br />
<br />
Some of the advantages of active filters includes similar frequency selectivity performance when compared to RLC circuits plus having passband gains greater than 1. Because these filters have OP AMP outputs, the chain rule applies in cascade design. Also, they do not require inductors which can be large, lossy and expensive, especially in low frequency applications.<br />
<br />
In active filter design, creating circuits realize a given transfer function T(s).<br />
<br />
The stages in the cascade are either first-order or second-order active filters. The real poles in T(s) are produced during first order building block developed earlier.<br />
<br />
The complex poles are produced by second-order building blocks. These second order filters will use the damping ratio and the undamped natural frequency parameters. Consequently, we design an active filter by controlling the poles introduced by each stage in a cascade connection.<br />
<br />
In the future, I will be providing sample videos in designing these active filters. However, you will need to have a knowledge of passive filter design as well as understanding the concepts of bode plots.Update: Engineering Tutorials and Planstag:freedomuniversity.ning.com,2010-02-24:1997874:BlogPost:50132010-02-24T03:40:46.000ZJohn Santiagohttp://freedomuniversity.ning.com/profile/JohnSantiago

Dr JOverview and Introduction to the z-Transform (Polynomial & Rational Functions)tag:freedomuniversity.ning.com,2009-07-06:1997874:BlogPost:35812009-07-06T12:53:25.000ZJohn Santiagohttp://freedomuniversity.ning.com/profile/JohnSantiago
Here's the first of a series on the z-Transform. Comments are welcomed.<br />
<br />
We introduce the z-transform bringing polynomials and rational functions to help analyze linear discrete-time systems. The discrete-time convolution (or FIR convolution) is equivalent to polynomial multiplication and algebraic operations in the z transform domain can be translated as combining or decomposing linear time-invariant (LTI) systems.

Here's the first of a series on the z-Transform. Comments are welcomed.<br />
<br />
We introduce the z-transform bringing polynomials and rational functions to help analyze linear discrete-time systems. The discrete-time convolution (or FIR convolution) is equivalent to polynomial multiplication and algebraic operations in the z transform domain can be translated as combining or decomposing linear time-invariant (LTI) systems. The most common z-transforms are rational functions, that is, the numerator polynomial divided by the denominator polynomial.<br />
<br />
We consider three representations of signals and systems. The first one, the time-domain or n-domain, involves sequences, impulse responses and differences. The next representation is the frequency or w-domain (omega-domain). Here, we consider frequency responses and spectrum descriptions. Finally and most important when analyzing discrete-time systems is the z-domain. This consist of z transforms, operators, and poles and zeros.<br />
<br />
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/i2_8p_N8urs&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="never"></param><embed src="http://www.youtube.com/v/i2_8p_N8urs&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="never" width="425" height="344"></embed></object>
<br />
One application of the z-transform is the use of the discrete-time convolution mentioned earlier. Here, the operation in the z-domain or z-transform domain involves multiplication between two polynomials. We'll see its the multiplication between the z transform of the input signal and the z-transform of the system or filter.<br />
<br />
The above application shows the value of having three different domain representation. A difficult analysis in one domain (discrete-time convolution) is simpler to analyze in the other domain (in this case the z-transform domain involving polynomial multiplication).<br />
<br />
Therefore, having increased understanding will result form developing skills for moving from one representation to another. The z transform domain exists primarily for its mathematical convenience in analyzing and synthesizing discrete-time signals and systems.Circuit Analysis - Thevenin Equivalent and Resistance - Part 1tag:freedomuniversity.ning.com,2009-04-18:1997874:BlogPost:28812009-04-18T15:45:24.000ZJohn Santiagohttp://freedomuniversity.ning.com/profile/JohnSantiago

Here is a Matlab demonstration using Simulink on synchronous detection.<br />
<br />
Synchronous detection is used to demodulate Double Sideband Suppressed Carrier AM (DSB-SC AM). Also known as coherent or homodyne detection, the scheme requires phase information to track the phase drift of the transmitted carrier in order for this detection scheme to work.<br />

Here is a Matlab demonstration using Simulink on synchronous detection.<br />
<br />
Synchronous detection is used to demodulate Double Sideband Suppressed Carrier AM (DSB-SC AM). Also known as coherent or homodyne detection, the scheme requires phase information to track the phase drift of the transmitted carrier in order for this detection scheme to work.<br />
<br />
A basic component used to achieve this detection scheme is a phase-locked loop (PLL) circuit. The PLL circuit is more complicated than the envelope detection scheme consisted of a simple diode and parallel connection between resisstor and capacitor (low-pass filter) to be discussed in a later article.<br />
<br />
In synchoronous detection, you need a local oscillator that is in-phase to the transmitted carrier and a low pass filter. The low pass filter gets rid of the high carrier frequencies and passes the low frequency message.<br />

<br />
Derived from the work of a British engineer Oliver Heaviside, the Laplace Transform remains a powerful tool and foundation in analyzing linear systems, especially involving feedback systems.<br />
<br />
Finding the system response using the classical differential equations is difficult. On the other hand, the Laplace Transform technique makes it a snap to find the solution but you gain further understanding of system behavior.<br />

<br />
<b>Part 1.</b> The video describes the definition of Laplace transform and its importance to analyzing system behavior. The operations performed in the Laplace domain involves algebraic manipulations and does not involve integrals and derivatives.<br />
<br />
Two examples are given. One is to find the Laplace Transform for a step input and the second example is finding the Laplace Transform of the exponential function defined over positive time.<br />

<br />
<br />
<b>Part 2.</b> The video shows how the Laplace Transform for an impulse function is a constant. So what is very thin in one domain is very wide in the other domain. An example of reciprocal spreading.<br />
