Submodules

torchcs.signal.pulses module

torchcs.signal.pulses.grpulse(Np=None, Tpr=[0.002, 0.09], Apr=[1, 5], Fs=5000.0, Ts=1.0, seed=None)

generates rectangular pulse

Parameters

  • Np (int or None, optional) – the number of pulses, by default None, which means generates randomly

  • Tpr (list, optional) – the range of pulse width, by default [2e-3, 100e-3]

  • Apr (list, optional) – the range of amplitudes, by default [1, 4]

  • Fs (float, optional) – the sampling frequency, by default 10e3

  • Ts (float, optional) – the sampling duration, by default 1.

  • seed (int or None, optional) – the seed for random number generator, by default None

Returns

generated signal tensor (\(N_s\times 1\))

Return type

tensor

The results shown in the above figure can be obtained by the following codes.

import torchbox as tb
import matplotlib.pyplot as plt

x = tb.grpulse(seed=2023)

plt.figure()
plt.grid()
plt.plot(x, '-b')
plt.xlabel('Time')
plt.ylabel('Amplitude')
plt.show()
