我想将我的Matlab代码转换为Python代码

Question

我想将Matlab代码转换为Python代码，以设计FIR滤波器。

%matplotlib notebook
import matplotlib.pyplot as plt
import numpy 
import array as arr

sample_rate = 48000
nsamples = 256

F = [1,15] * 1000
A = [1,0.5]

t = [0,nsamples-1] / sample_rate


fvtool(fir_coeff, 'Fs', sample_rate)


filtered_signal = filter(fir_coeff, 1, signal)

我期望得到FIR过滤图。谁能给我一些帮助/建议？
