The power spectrum of a signal can be calculated by taking the magnitude squared of its Fourier transform. Being an audio person, the signal of interest for me would be a time series.
How does this ...
My question is regarding how one could/should smooth a rather noisy power spectrum obtained from measurements. There are various methods one can use (a moving average, binning, etc) and I am not sure ...
There are lots of spectrum estimation techniques, each with some pros and cons.
Yule-Walker AR method
modified covariance method
multitaper method (...
