By doctorj, on November 15th, 2009% One of many videos on digital signal processing. Initial background is needed to discuss the basics of DSP. Here, we talk about the remarkable mathematical relationship and formula known as Euler’s formula. Some of the links in the post above are “affiliate links.” This means if you click on the link and purchase the item, [...] . . . → Read More: Digital Signal Processing (DSP) Tutorial: Euler’s Formula – Part 1
By doctorj, on July 6th, 2009% In analog or continuous systems the Fourier transform played a key role in analyzing signals and systems. The inverse z transform represents a timedomain sequence of a z transform function. We note that the z transform for digital signals or discretetime signals is the digital counterpart of the Laplace transform for continuoustime signals. Both the [...] . . . → Read More: zTransform Tutorial: zTransform and Inverse zTransform Examples & Functions
By doctorj, on July 5th, 2009% We introduce the ztransform bringing polynomials and rational functions to help analyze linear discretetime systems. The discretetime 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 timeinvariant (LTI) systems. The most common ztransforms are rational functions, that is, the [...] . . . → Read More: Overview and Introduction to the zTransform (Polynomial & Rational Functions)
By doctorj, on February 27th, 2009% 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. ztransform) Some of the links in [...] . . . → Read More: Matlab Examples: Review of Discrete Convolution Sum Using Matlab
