2nd Experiment
This experiment required us to take x(n) and calculate its Fourier Transform. This experiment included two cases. First case was done using N=4 and second case was with N=8. The second case was done by adding zeroes to the x(n) with N=4.Also IDFT was calculated from the X[k] obtained in the first part of the experiment.
As N increased the frequency spacing reduced and the resolution of the the spectrum increased.
Also we saw LC by CC
ReplyDeleteDFT always give periodic results and increasing the length by zero padding of signal gives better approximation of signal and resolution of spectrum increases.
ReplyDeleteBy appending the input sequence by zeros the resolution error reduces
ReplyDeleteError reduces as well
Deleteby appending more zeroes, the missing values in less point DFT are present in the DFT with more point.
ReplyDeleteResolution gets better
