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?
Calculate the Small Signal Voltage Gain a) Calculate the small signal voltage gain a v = v o /v i , input resistance R i , and output resistance Ro for the circuit below. A
Q. Give the principle of biasing a FET amplifier. To correctly bias the FET, the gate needs to be negative with respect to the source. Bias is obtained in the following manner:
