How do I zero the rigion of the FFT output before plotting? The zero frequency region will be at the left hand side of the output plot:
I would like to zero the high value peaks at the extreme ends of th eplot and replot to bring up the signals in between.
How would I zero this region?
This is parts of the code of the algorithm:
t = sym(1):1:sym(P); % Signal duration/length
fncT = (T.^t) - floor(T.^t/M)*M; % Alternative version to mod(a,b)
% Fast fourier Transforms 1-D
A = fftshift(double(fncT)); % Rearranges 'fncT' by shifting the zero-frequency component to the centre of the array
A = fft(A); % Computes duscrete fourier transform of A using fft algorithm
A_mag = abs(A.*A);
