如何将信号离散化？

Question

如果我有如下功能：

G(s)= C/(S)，其中s=jw，c和p是常数。

另外，可用的频率是wa= 100000 rad/s，如何在∆w = 0.0001wa的情况下对信号进行离散化？

Answer 1

使用numpy.arange实现这一点：

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]
