如何离散化信号？

Question

如果我有如下函数：

G(s)= C/(s-p) where s=jw, c and p are constant number.

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

Answer 1

使用numpy.arange完成这个：

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]
