The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the...

The signals presented here can be used in demonstrating how the signal varies when the operation is made on either independent variable or dependent variable. The parameters can be varied to have a feel of the variation.Example(1): rect(1,2) plots the rectangular signal of amplitude 1 and a width...
