Hi all!
I am a newbie to DSP. I have some basic questions. I will reall
appreciate if someone answers them.

1. Is it logical to perform 1024 point FFT on a vector of size less tha
1024 (say 150) in MATLAB ?
2. If yes, then -does MATLAB perform zero padding automatically in abov
case or do we need to do it manually ?
3. what kind of output will it give ?
