Hi all, My Question is: Is FFT applicable to a non-uniformly sampled signal?. I heard from one of my friends that we can apply DFT to a N-US signal and not FFT. Is this correct? And also how is the nyquist rate defined for a non uniformly sampled signal?. looking forward to your replies..... bye __________________________________________________ |

Simha J- Nyquist, DFT, etc. theory is based on linear time-invariant system. First interpolate your signal to match or exceed the smallest interval between samples; i.e. make uniformly sampled. Then proceed.
