Power Spectral Density is a measure that describes how the power of a signal is distributed across different frequencies in the frequency domain. Definition: - PSD represents the power per unit bandwidth (W/Hz) as a function of frequency - Mathematically: S(f) = X(f)²/T, where X(f) is the Fourier...
