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?
Explain the purpose of the I/O instructions IN and OUT. The IN instruction is used to move data from an I/O port into the accumulator. The OUT instruction is used to move d
Q. What is inter digit time? Break time is nominally 61 ms and make time is nominally 39ms. Digits are separated by idle period of 300 ms known as inter digit time. It is vital

LC Filter To the load resistance R L the ripple factor is directly proportional in the inductor filter and inversely proportional to R L in the capacitor filter. Hence i
What is synchronous data transfer? It is a data method which is used when the I/O device and the microprocessor match in speed. To transfer a data to or from the device, the us
If E b /N 0 = 20 in a coherent ASK system, find the value of Eb/N0 that is needed in a noncoherent ASK system to yield the same value of Pe as the coherent system.
