Can you average an FFT?
You can perform averaged measurements on an FFT channel to improve measurement accuracy or to help compensate for a low signal-to-noise ratio.
What is ensemble averaging?
Ensemble averaging is a data acquisition method that enhances the signal-to-noise of an analytical signal through repetitive scanning. Ensemble averaging can be done in real time, which is extremely useful for analytical methods such as: Nuclear Magnetic Resonance Spectroscopy (NMR)
What is the frequency range of FFT?
The output of the generic FFT normally used in programming is 0-22khz for a 44.1 sample and 0-24khz for a 48khz input.
