In signal processing, the energy of a signal is given by Assuming the total energy is finite (i.e. is a square-integrable function) allows applying Parseval''s theorem (or Plancherel''s theorem). That is, where is the Fourier transform of at frequency (in Hz). The theorem also holds true in the discrete-time cases. Since the integral on the left-hand side is the energy of the signal, the value of can be interpreted as a density function multiplied b

What is the Power Spectral Density (PSD)?
In this lesson, we will break down the three pivotal elements of the PSD—power, frequency spectra, and density—and discuss the significance of
In, the of a signal is given by Assuming the total energy is finite (i.e. is a ) allows applying (or ). That is, where is the of at (in ). The theorem also holds true in the discrete-time cases. Since the integral on the left-hand side is the energy of the signal, the value of can be interpreted as a multiplied b
