Write an m-file "sampling.m", which will take as an input: a signal and a sampling step and will display the sampled signal and the magnitude of its Fourier transform. sampling.m
function sampling(x,step) plot(x(1:step:end),'-o') plot(abs(fft(x(1:step:end))))
use x as the input signal
x=(sin([0:pi/8:4*pi]))
Run the function with step=1.Increase the sampling step 2,4,8.... and observe what happens with the spectrum.
What happens with the spectrum as the sampling step increases?
What should be the minimum sampling frequency (maximum sampling step) of a signal?

Execution Unit receives program instruction codes and data from BIU, implements these instructions and store the result in general registers.
why we plot graph to find bandwidth is drawn b/w av/avmax v/s frequency not av v/s frequency?
In order to demonstrate aliasing, make a plot of the signal x(t) = 3 cos 2π10t - cos 2π30t which approximates a square wave with W = 30 Hz. If the sample points are taken at
