By doctorj, on September 11th, 2011% One common class of signals are sinusoids…that is they are either cosines or sines. The video shown below briefly reviews the definition of a sine, cosine, and tangent. [tubepress mode="tag" tagValue= 'soh cah toa drjctu'] Mathematically, the cosine signal is generally given as (Equation 1) where is the angular frequency (radians/sec), f is the [...] . . . → Read More: Signal Processing Tutorial: The Basic Sinusoids
By doctorj, on September 9th, 2011% 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
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 November 15th, 2009% This is an introduction to digital signal processing. Here, we begin with an background introduction with geometric series and its application to finding the Fourier Transform for discretetime signals. Note when we talk about discretetime signals the example given in the video is for aperiodic signals. Signals that are continuous or discrete in the timedomain [...] . . . → Read More: Digital Signal Processing (DSP) Tutorial: Introduction to Geometric Series and the DiscreteTime Fourier Transform
