Hi,

I am trying to simulate fft of a sinewave of certain frequency with
Modelsim.

To simulate the fft code, first we have to find the Bin size. I have
found that.

Bin size = ( i/p freq*point fft)/sampling rate. (point fft = 1024)

For a sine wave of i/p freq 10Hz, and Fs = 50Hz, bin size is 204.8.

FFT of a sine wave is a delta at a frequency same as that of the input
frequency. Now how do i view this in the simulator. Please guide me.

thanks in advance.
Parvathi.
