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(2np.pi10*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)))
