This website includes a Java applet that displays the effect that various operations on an N-periodic, discrete-time signal (e.g. time shift, time scale, filtering) have on the signal and its spectra. Sketch the signal...
For the phasor phanatic, created Hsi Chen Lee of Johns Hopkins University, an applet that offers 4 ways to generate and observe continuous-time harmonic phasor sums and the corresponding fourier series.
Created by Lang Moore for the Connected Curriculum Project, the purpose of this module is to study the Fourier transform and use it to describe solutions of the heat equation on an infinite rod. This is one of a much...
This resource from Johns Hopkins University has audio and interactive components. Various forms of the Fourier series description for periodic signals are based on alternate ways of writing a cosine signal. This...
