What is a cross spectrogram?

Cross-Spectrogram of Complex Signals

Generate two signals, each sampled at 3 kHz for 1 second. The first signal is a quadratic chirp whose frequency increases from 300 Hz to 1300 Hz during the measurement. The chirp is embedded in white Gaussian noise.

What is cross power spectrum?

Cross power spectral density ❲CPSD❳, or cross-spectrum, is a spectral analysis that compares two signals. It gives the total noise power spectral density of two signals. The only condition is that there should be some phase difference or time delay between these two signals.

What is cross spectral analysis?

Analysis. The cross-spectral density (CSD) is one of several advanced graph functions used to compare signals. Specifically, it displays the distribution of power for a pair of signals across a frequency spectrum at any time. This information can be used to determine the influence of a signal in relation to another.

How does MATLAB calculate spectrum?

In MATLAB®, the fft function computes the Fourier transform using a fast Fourier transform algorithm. Use fft to compute the discrete Fourier transform of the signal. y = fft(x); Plot the power spectrum as a function of frequency.
