matplotlib.pyplot. phase_spectrum (x, *, Fs = None, Fc = None, window = None, pad_to = None, sides = None, data = None, ** kwargs) [source] # Plot the phase spectrum. Compute the phase spectrum (unwrapped angle spectrum) of x .

Feb 18, 2020 · 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 …

Compute and plot a spectrogram of data in x. Data are split into NFFT length segments and the spectrum of each section is computed. The windowing function window is applied to each segment, and the amount of overlap of each segment is specified with noverlap. The spectrogram is plotted as a colormap (using imshow).

Dec 11, 2024 · In this example, we use np.unwrap () to remove the discontinuities in the phase spectrum before we plot the phase spectrum in Python using Matplotlib. This can often provide a clearer view of the underlying phase behavior.

The plots show different spectrum representations of a sine signal with additive noise. A (frequency) spectrum of a discrete-time signal is calculated by utilizing the fast Fourier transform (FFT).

Sep 12, 2018 · The default period argument of np.unwrap is 2 pi, but you are trying to unwrap by pi. Call it like this: plt.plot(np.unwrap(phase, period=np.pi))

Mar 6, 2024 · To avoid discontinuities in the phase spectrum plot, phase angles can be unwrapped using the np.unwrap function. This method changes abrupt jumps by 2π to their 2π complement. Here’s an example:

Mar 6, 2024 · In this article, we discuss how to plot an angle spectrum—also known as a phase spectrum—using Matplotlib in Python. Readers will learn methods for effectively visualizing angles, ranging from simple plots to more complex circular representations.

Apr 21, 2020 · In Python, the magnitude_spectrum() method in the pyplot module of Python matplotlib library plots the magnitude spectrum of a periodic signal. Below are some programs which demonstrate the use of magnitude_spectrum() method to visualize the magnitude spectrum of different periodic signals.

Jan 19, 2022 · For this visualization specgram () function is used with the required parameters. Syntax: matplotlib.pyplot.specgram (Data, NFFT=None, Fs=None, Fc=None, detrend=None, window=None, noverlap=None, cmap=None, xextent=None, pad_to=None, sides=None, scale_by_freq=None, mode=None, scale=None, vmin=None, vmax=None, *, data=None, **kwargs) Parameter:
