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?

Determine the voltage transfer function of the high-pass filter circuit shown in Figure, and find the expression for ω 0 .
Q. Given the block diagram and the truth table of a demultiplexer, as shown in Figure, obtain its implementation.
Q. What do you mean by Frequency Response? As with all electronic circuits, op amps have limited frequency response. Because of the negative feedback of the circuit, the passba
