python代码实现密勒编码波形输出
Python代码实现密勒编码波形输出可以使用Numpy库的fft函数来实现：
import numpy as np
# generate a time vector t from 0 to 1 second with 1000 samples
t = np.linspace(0,1,1000)
# generate the input signal x as a sine wave of frequency 10 Hz
x = np.sin(2*np.pi*10*t)
# calculate the Fast Fourier Transform (FFT) of x using numpy's fft function
X = np.fft.fft(x)
# calculate the magnitude spectrum of X and normalize it to 0 dBFS (Full Scale) level magX = 20 * np.log10(np.abs(X)/np.max(np.abs(X)))
