Here I convolve an input signal, f, with a system impulse response, g, and plot the results, y = f*g, at each step of the computation. This GIF shows the processes involved in computing the discrete convolution. The steps are flip, slide, and sum. The impulse response, g, is flipped about the origin then a discrete sum is calculated at each incremental shift to obtain the updated output convolution. As you watch the video, note the following...
1. The convolution is the product of the overlapping areas as the signal is shifted. 2. The output signal peaks when both signals overlap completely. 3. The original signals both have non-zero values between 0 and 4 units. The output has non-zero values between 0 and 8 units.
