What is Wiener-Khinchin theorem in digital communication?
The Wiener-Khinchin theorem states that, under mild conditions, SX(f)= ˆRX(f), i.e., that the power spectral density associated with a wide-sense stationary random process is equal to the Fourier transform of the autocorrelation function associated with that process.
What is Wiener-khinchin theorem * Mcq?
5. What is Wiener-Khinchin theorem? Explanation: According to the theorem spectral density of a signal x(t) and auto correlation function makes a fourier tranform pair.
What is power spectrum of a signal?
The power spectrum of a signal indicates the relative magnitudes of the frequency components that combine to make up the signal. The data used to determine the power spectrum must reflect sufficient excitation in the signal.
