Plotting Fourier Transform - HELP PLEASE
显示 更早的评论
Consider a pulse of amplitude 1 and time duration 1 second. Sample this pulse at 20 samples/sec for 20 seconds and compute and plot the Discrete Fourier Transform (DFT).
I need the matlab code for this problem. I have not much knowledge of matlab.
Thank you very much

Insufficient information about the shape of the pulse.

I assume the professor is asking for a rectangular pulse, but as you said, it is impossible to know for sure...
