A convolution is a way to combine two sequences, x and w, to get a third sequence, y, that is a filtered version of x. The convolution of th...

The sampling theorem states that a continuous signal x(t) bandlimited to B Hz can be recovered from its samples x[n] = x(n*T), where n is an...

Spectrum analysis is the process of determining the frequency domain representation of a time domain signal and most commonly employs the Fo...
