What is bi-spectrum of signal

The bispectrum is a tool for analyzing signals. While the power spectrum of a signal breaks down the power of a signal by its frequency, the bispectrum provides information regarding specific interactions between the various frequency components of a signal.

What is Bispectrum analysis of EEG?

The Bispectrum quantifies the relationship among the underlying sinusoidal components of the EEG. Specifically, Bispectrumanalysis examines the relationship between the sinusoids at two primary frequencies, f₁ and f₂, and a modulation component at the frequency (f₁ + f₂).

What is spectrum in signal and system?

The signal spectrum describes a signal's magnitude and phase characteristics as a function of frequency. The system spectrum describes how the system changes signal magnitude and phase as a function of frequency. For example, Figure 6.6 shows the magnitude and phase spectra of some hypothetical system.

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.

What is spectrum analysis DSP?

Spectral analysis is the process of estimating the power spectrum (PS) of a signal from its time-domain representation. Spectral density characterizes the frequency content of a signal or a stochastic process.
