Re: Nyquist frequency & odd even FFT

Reply posted 2 years ago (10/04/2021)
Yes that sounds right to me. For an odd FFT of 1001 samples, the highest frequency bin represents 0.4995 and the lowest -0.4995.Neither of which are actually...

The odd fft doesnt have a frequency bin @ the nyquist.the frequency bins are determined by k/N if N is odd then k/N can never be equal to 0.5.For N = 10, These...

If you have an even fft you will have one bin at the nyquist frequency.The reason there is only 1 is because the +nyquist is identical to -nyquist.The DFT correlates...
