Hi there,
I am trying to observe the behaviour of the fourier trasform of the sinc function if some of its zeros will be removed. Normally, the sinc function will lead us to rectanglular function in fourier domain, but when I am trying to remove the zeros at 'pi' it is not showing anything due to NaN or infinite. May I request you to pls tell me how to deal with such problem?
Fs=42;Ts=1/Fs;t=-1:Ts:40*Ts-Ts;f=5;y=sinc(t*f)/(1-5*t/(0.9)*pi);figure;plot(t,y);xlabel('x');ylabel(' magnitude');fy=fft(y);%figure;
% plot(fy)
fy = fftshift(fy);figure;plot([abs(fy)])%;angle(fy);real(fy);imag(fy)]','*')
