Question

what is the unit of spectral energy density​

Answer 1

Explanation:

The power spectral density (PSD) of the signal describes the power present in the signal as a function of frequency, per unit frequency. Power spectral density is commonly expressed in watts per hertz (W/Hz).

Answer 2

Answer:
