Discrete-Time Convolution Example (Inverse z-Transform)

You can view the convolution as the inverse z-Transform of Y(z)=H(z)U(z) where Y(z), H(z), and U(z) are the Laplace Transform of the output response, impulse system response, and input signal, respectively. DVDs are in progress and are based on market demand on selected topics.

STUDENTS STUFF AND WRITING TIPS AND HELP

When starting to work on a Research Paper outline, sit down and focus on sub topics of their main topic, so-called additional questions – they add new details to their problem and help make a Research Paper more complete. Now look at how students may prove these points to be true, and supplement their ideas with facts. Now students have something that has to be organized into a logical sequence with smooth transitions.

A Research Paper outline has to be crowned with one important text… Continue

Essay Writing Help

An outline for a Best Essay writing is basically 60 per cent of work done. While writing a term paper outline, students basically write main parts of assignment. Admit it – it’s much easier to adjust or rewrite several points in an outline than rewriting a whole paragraph or even several paragraphs in a term paper itself.

Matlab Examples - Amplitude Demodulation Using Synchronous Detection

Here is a Matlab demonstration using Simulink on synchronous detection.



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.



A basic component used to achieve this detection scheme is a phase-locked loop (PLL) circuit. The PLL circuit is more complicated… Continue

Matlab Examples - Amplitude Modulation

Here is an example using Matlab's Simulink to demonstrate the concept of Amplitude Modulation. Two types of amplitude modulation schemes are discussed: Double Sideband Suppressed Carrier (DSB-SC) AM and Double Sideband Large Carrier (DSB-LC) AM. DSB-LC AM is used your standard and commercial AM… Continue

Origami Folding Instructions - Base Folds

Base folds are basic forms serving as a basis for more creative origami figures. They are easy to do and will become like second nature while watching TV. With the appropriate base fold selected, you can bring new creations to life, especially with stop action animation.



You can use these origami figures for animation which in turn can be used to demonstrate sampling.
