如何离散化信号？

Question

如果我有如下功能：

  

G（s）= C /（s-p），其中s = jw，c和p为常数。

此外，可用频率为wa = 100000 rad / s。如何在Python中将∆w = 0.0001wa的信号离散化？

Answer 1

使用numpy.arange完成此操作：

import numpy as np

wa = 100000
# np.arange will generate every discrete value given the start, end and the step value
discrete_wa = np.arange(0, wa, 0.0001*wa)

# lets say you have previously defined your function 
g_s = [your_function(value) for value in discrete_wa]
