the rectangular pulse is “interpreted” by the DFT as a spectral line at frequency ω = 0. EE 524 Fall 2004
The important point of this example and the sinc function example is that once a transform The MATLAB function hamming(L) computes a vector with values given ...

One might guess that the. Fourier transform of a sinc function in the time domain is a rect function in frequency domain. This turns out to be correct as could
The MATLAB command to plot a graph is plot(xy)

7-1 DTFT: Fourier Transform for Discrete-Time Signals Another common signal is the L-point rectangular pulse which is a finite-length time.
The impact of applying the rectangular window (i.e. function) in the time domain is When you use the Matlab function fft(sig) to compute the spectral ...
Solution: Use MATLAB to plot the signal c(t) = cos(2 ? f0 t) rect(t - ½) for -0.5 We then lookup the Fourier transforms of cosine and rectangular pulse:.
