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[sound,]
returns the squared power spectrum of sampled sound object.
