PeriodogramArray

PeriodogramArray[list]

returns the squared magnitude of the discrete Fourier transform (power spectrum) of list.

PeriodogramArray[list,n]

averages the power spectra of non-overlapping partitions of length n.

PeriodogramArray[list,n,d]

uses partitions with offset d.

PeriodogramArray[list,n,d,wfun]

applies a smoothing window wfun to each partition.

PeriodogramArray[list,n,d,wfun,m]

pads partitions with zeros to length m prior to the computation of the transform.

PeriodogramArray[image,]

returns the squared power spectrum of image.

PeriodogramArray[audio,]

returns the squared power spectrum of audio.
