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 junction transistors (npn and pnp). Junction Transistor: This transistor consists of two p-n junctions combined in one crystal as demonstrated in figure below.
What do you understand by orthographic projection ? Illustrate with the help of Matrix representation.
Case 1 (B>A) Suppose XX = 01H ( stored in a) and YY = 03H (stored in B).then carry flag will set by CMP instruction since B>A in this case JNC will not transfer the e
