z-Transform Tutorial: z-Transform and Inverse z-Transform Examples & Functions
In analog or continuous systems the Fourier transform played a key role in analyzing signals and systems. The inverse z transform represents a time-domain sequence of a z transform function. We note that the z transform for digital signals or discrete-time signals is the digital counterpart ...Overview and Introduction to the z-Transform (Polynomial & Rational Functions)
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 ...Matlab Example - Bode Plots of a Low Pass Filter (Part 2)
The Matlab tutorial article continues with providing an example of a low pass filter (LPF) to graph its bode plot in Matlab. The low pass filter was implemented using a simple RC-circuit. To review, bode plots are basically logarithmic graphs of a linear time-invariant system as a function of frequency. ...Simulink / Matlab Tutorial and Example - Low Pass Filter (Part 1)
The Matlab tutorial provides a quick introduction describing a low pass filter (LPF). A LPF passes low frequency signals while attenuating the amplitude of signals with higher frequencies at a frequency called the cutoff frequency. The cutoff frequency determines when frequencies of the input signal passes through the ...OpAmp Design & Application Tutorial - Binary-Weighted Digital-to-Analog Converter (DAC) - Part 2
The previous video provided an introduction on the digital-to-analog converters (DACs). Here, we show how a binary-weighted inverting summer using operational amplifiers (op amps). We used the same example for 4 bits digital input. The summer inputs are applied to the binary-weighted input resistors, respectively. The ...OpAmp Design & Application Tutorial - Digital-to-Analog Converter (DAC) Intro - Part 1
OP AMP circuits are the basic building blocks to meet a wide a variety of signal processing applications. These applications include: instrumentation, sensor monitoring, process control, filtering, analog-to-digital converters, and digital-to-analog converters. The first application is the digital to analog converter (DAC) and this video will be an ...Op Amp (Operational Amplifier) Design and Circuit Tutorial (Part 3)
We use the same example from the previous article. The video will show once again how to go from an input-output relation described as an algebraic equation to a block diagram form. In this design, we use fewer number of op amps to implement a circuit describng the equation. To ...Op Amp (Operational Amplifier) Design and Circuit Tutorial (Part 2)
Op AMP circuit analysis can find input-output relationships for a given circuit configuration. Say we're given an equation or block diagram model of a signal-processing function. Several OP AMP design circuits are tied together to realize the equation or signal-processing function. Again, there are no unique answers ...Op Amp (Operational Amplifier) Design and Circuit Tutorial - Interface Design - Part 1
A series of videos showing how to do interface design using operational amplifiers. The videos shows how to maximize the power delivered to a load using a noninverting design and an inverting design. Loading effects of the inverting design are briefly discussed.Laplace Transform Video Tutorial and Inverse Laplace Transform Tutorial - Part 1
Here is one of my early videos I did using Camtasia discussing the topic about Laplace Transforms. I planned to redo this video in a future post. An important concept in engineering concerns the Laplace Transform. Applying this important concept in electrical engineering, the Laplace Transform takes a function described in ...Groups

Circuit Analysis - Thevenin Equivalent and Resistance - Part 1
Usually, signals from another circuits feeds into a another part of a circuit, called a load circuit. The one generating the signal is called the source circuit. This interaction between the source and load circuit at the interface is a key design issue.
One of the most valuable analytical tools to help simplifly and deal… Continue
