Signal Processing Tutorial: Introduction to Signal Processing

An Introduction to Signal Processing Signal processing involves signals and systems. Today, you have multimedia computers, entertainment systems and digital communications systems and you can be sure that signal processing functions are involved. When it comes to the meaning of signals, you may be thinking of a signal as carrying information. Usually, that information is [...] . . . → Read More: Signal Processing Tutorial: Introduction to Signal Processing

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 most common z-transforms are rational functions, that is, the [...] . . . → Read More: Overview and Introduction to the z-Transform (Polynomial & Rational Functions)

Matlab Examples: Review of Discrete Convolution Sum Using Matlab

Here is a review of the discrete convolution sum including several examples using Matlab. The convolution concept is very important in the area of digital signal processing with applications to communications and control systems. You can also view the discrete convolution sum as a multiplication of two polynomials (e.g. z-transform) Some of the links in [...] . . . → Read More: Matlab Examples: Review of Discrete Convolution Sum Using Matlab

Introduction to Circuit Analysis

I plan to start a series of videos on circuit analysis. In particular we will be studying Linear Circuits. We’ll begin with some terminology and variables of electrical engineering used throughout the video series. Of course, some of more important concepts include voltage and current and its associated laws of Kirchoff’s Voltage Law (KVL) and [...] . . . → Read More: Introduction to Circuit Analysis
