How do you calculate power from power spectral density?

A signal consisting of many similar subcarriers will have a constant power spectral density (PSD) over its bandwidth and the total signal power can then be found as P = PSD · BW.

What is amplitude spectral density?

The Amplitude Spectral Density is also used to analyze noise signals. It has units of V/√ Hz in the analog domain and. FS/√ Hz in the digital domain. The Amplitude Spectral Density is simply the square root of the Power Spectral Density. FFT Windows and the Equivalent Noise Bandwidth (ENBW)

How do you find the amplitude spectrum of a signal?

The shape of the amplitude spectrum is determined by the function sin( f ) f π τ π τ . the single rectangular pulse of width τ contains all frequencies between 0 and ∞. the relative amplitudes (ignoring the overall amplitude factor) of these frequencies is given by the function sin( f ) f π τ π τ .
