what is the advantage as the point of fft increases? I know that if the N point is greater than the length of the signal, zeros are added at the end of the signal.
But I'm not sure of the advantages of zero padding of the signal. What exactly does N point mean and zero padding advantage in doing fft?
And if you add an enormous number of zeros, in the gain in terms of fft better?
Homework Answers
The N point FFT of a sequence x[n] is given
and the sequence is given as
So N-point FFT assumes that the sequence x[n] is periodic with period N and hence it can have only discrete frequencies from 0 to 2pi at the spacing of 2pi/N. So the frequency resolution is proportional to the no of points.
Lets assume that the length of sequence is M and we are taking N points FFT where M < N. So we have
and
So the N point FFT equation becomes
Or
Since no of terms inside the summation is lesser (M < N), the gain decreases.

DFT can also be obtained using matrix multiplication. Let X[r] show the transformed values and x[n] show the original signal. Using the analysis equation: Using matrix multiplication, this operation can be written as x[O X[1 1 e(2m/N) e-K4n/N) x12] [N-1]] e-j(2(N-1)T/N)e-j(4(N-1)m/N) Instead of huilt-in EFT function use matrix multinlication to solve 3th auestion [ 1 e-/(2(N-1)(N-1)T/N)]Le[N-1] DFT is an extension of DTFT in which frequency is discretized to a finite...

3.2 Simple Bandpass Filter Design The L-point averaging filter is a lowpass filter. Its passband width is controlled by L, being inversely proportional to L. In fact, you can use the GUI altidemo to view the frequency response for different averagers and measure the passband widths. It is also possible to create a filter whose passband is centered around some frequency other than zero. One simple way to do this is to define the impulse response of an L-point FIR...
