如何使用python为简单的正弦波输入生成反冲信号？

import numpy as np
import matplotlib.pyplot as plt

def generate_reversal_signal(amplitude, frequency, duration, sample_rate):
    # 生成时间序列
    t = np.arange(0, duration, 1/sample_rate)

    # 生成正弦波信号
    sine_wave = amplitude * np.sin(2 * np.pi * frequency * t)

    # 生成反冲信号
    reversal_signal = -1 * sine_wave

    return t, reversal_signal

# 设置参数
amplitude = 1.0         # 振幅
frequency = 5.0         # 频率
duration = 2.0          # 信号时长（秒）
sample_rate = 1000      # 采样率

# 生成反冲信号
t, reversal_signal = generate_reversal_signal(amplitude, frequency, duration, sample_rate)

# 绘制信号图形
plt.plot(t, reversal_signal)
plt.xlabel('Time (s)')
plt.ylabel('Amplitude')
plt.title('Reversal Signal')
plt.grid(True)
plt.show()
