WebFeb 11, 2024 · Finding RMS Noise from the Power Spectral Density (PSD) We know that S X (f) specifies the power of the noise waveform X in 1-Hz bandwidth around f. Since we know that, we can calculate the total noise power over a given bandwidth by calculating the total area under S X (f) in that frequency band. In physics, the signal might be a wave, such as an electromagnetic wave, an acoustic wave, or the vibration of a mechanism. The power spectral density (PSD) of the signal describes the power present in the signal as a function of frequency, per unit frequency.
