MATLAB Online에서 열기 You have to get the dataspectrogramproduces and plot it separately: T = 0:0.001:2; X = chirp(T,100,1,200,'q'); [S,F,T] = spectrogram(X,128,120,128,1E3,'yaxis'); figure(1) surf(T,F,abs(S)) ...

Open in MATLAB Online Ran in: Hi all, To plot the output of the spectrogram signal do the following (example with a toy signal): fs = 1000; t = 0 : 1 / fs : 2; x = chirp( t, 100, 1, 200,'quadratic'); [ X, f, t, S ] = spectrogram( x, 128, 120, 128,...
center.If the function you are using is the MathWorks' version of spectrogram, then you are plotting a complex-valued function. I don't really see the use case for wanting to do that. I can see wanting to plot the magnitude and phase separately, but that is not what plot(spectrogram(x...
Open in MATLAB Online I prefer the pspectrum function for these analyses. See specifically Spectrogram and Reassigned Spectrogram of Chirp for an example of returning the data and plotting it as well. ThemeCopy data = readmatrix('D:\Data_tokamak\data\obp.txt'); x_data = data(:...

how to I convert continuous data with high frequency transient events to a spectrogram to demonstrate the occurence of the events using wavelets and spectrograms? I have non-stationary continuous data, sampled at 1000 Hz with transient oscillatory activity embedded. The main a...
Does anyone know how to plot actual time interval in Spectrogram using STFT? I want to analyze an event in a signal in a certain time span, but using the spectrogram built in function plots in Spectrogram from 0, while I want it to be plotted from for exp. 5083s time span as seen ...
