Plot phase spectrum
WebbI was expecting the phase spectrum alternates -pi/2 and pi/2, but the graph(too bad that I cannot post it due to lack of my reputation) shows me that X_angle gradually increases … Webb2 apr. 2024 · The phase_spectrum () function in pyplot module of matplotlib library is used to plot the phase_spectrum. Generally, it compute the phase_spectrum of sequence and plotting is done. Syntax: phase_spectrum (x, Fs=2, Fc=0, window=mlab.window_hanning, pad_to=None, sides=’default’, **kwargs)

Webb18 feb. 2024 · phase_spectrum does three things different than you: It applies phase unwrapping. If you want to apply phase unwrapping in your code, just do np.unwrap (np.angle (Y)). If you want matplotlib to plot the spectrum without unwrapping, use angle_spectrum instead. It applies a windowing function to the data before computing … WebbThe easiest way to plot the spectrum of this transfer function is to plot the first-order term first, then rescale the vertical axis of the magnitude spectrum so that 0 dB is equal to …
Webbfor plotting magnitude spectrum versus frequency you can use the following script: t = 0:0.001:0.2; s = sin(2*pi*100*t)+cos(pi*500*t); S = abs(fftshift(fft(s))); Fs = 1000; df = … Webb26 aug. 2024 · Check the documentation maybe.
