Learn more about spectrogram, matlab, array MATLAB spectrogram error in matlab. Learn more about spectrogram Signal Processing Toolbox spectrogram(x2,[],[],[],fs, 'yaxis') You can notice that the two spectrograms are similar except for a difference in the magnitudes of the power because they are represented in different units. In the first case, the units is dB/rad/sample while the second representation uses dB/Hz.

Learn more about spectrogram, matlab, array MATLAB 'onesided' — Returns the one-sided cross-spectrogram of a real input signal. If nfft is even, then s has nfft/2 + 1 rows and is computed over the interval [0, π] rad/sample. If nfft is odd, then s has (nfft + 1)/2 rows and the interval is [0, π) rad/sample. If you specify fs, then the intervals are respectively [0, fs/2] cycles/unit time and [0, fs/2) cycles/unit time.

NumBands and fs determine L. s = xspectrogram (x,y) returns the cross-spectrogram of the signals specified by x and y. The input signals must be vectors with the same number of elements. Each column of s contains an estimate of the short-term, time localized frequency content common to x and y. specgram computes the windowed discrete-time Fourier transform of a signal using a sliding window.
