如何使用 UliEngineering 在 Python 中去除信号的直流偏移
你可以使用 UliEngineering Python 库轻松去除信号的直流偏移（均值）：
remove_mean.py
import numpy as np
from UliEngineering.SignalProcessing.Utils import *
# 创建一个带有直流偏移的信号
signal = np.array([1.0, 2.0, 3.0, 4.0, 5.0]) + 10.0
# 去除直流偏移
signal_centered = remove_mean(signal)
print(f"Original signal mean: {np.mean(signal)}")
print(f"Centered signal mean: {np.mean(signal_centered)}")
print(f"Centered signal: {signal_centered}")示例输出
remove_mean_output.txt
Original signal mean: 12.0
Centered signal mean: 0.0
Centered signal: [-2. -1. 0. 1. 2.]remove_mean() 函数从信号中减去算术平均值，从而将信号以零为中心进行居中处理。
