psd

Block Category: Matrix Operation

Description: The psd block accepts a vector of signal values and generates a vector of power spectrum values. The psd block performs an FFT on the input vector then transforms the FFT to represent power versus frequency. To capture all the power spectrum information, plot the output on a Log Y plot.

The change in frequency of the psd output vector equals
