By doctorj, on November 17th, 2009% If and when technical subjects like physics or engineering are to be taught online interactive simulations and experiments must be available to reinforce important concepts. Here is one resource that provides fun, interactive, research-based simulations of physical phenomena from the PhET(Physics Education Technology) project at the University of Colorado. This is an ongoing project with [...] . . . → Read More: Interactive Simulations and Animations for Teaching Physics, Chemistry, and Physical Science
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. . . . → 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 discrete-time signals. Note when we talk about discrete-time signals the example given in the video is for aperiodic signals. Signals that are continuous or discrete in the time-domain [...] . . . → Read More: Digital Signal Processing (DSP) Tutorial: Introduction to Geometric Series and the Discrete-Time Fourier Transform
