绘制Python中的斜坡脉冲函数

import numpy as np
import matplotlib.pyplot as plt

start_time = 0   # 起始时间
end_time = 1     # 结束时间
slope = 1        # 斜坡的斜率
amplitude = 1    # 脉冲幅度

time = np.linspace(start_time, end_time, num=1000)  # 生成从起始时间到结束时间的等间隔时间点

signal = np.where(time >= start_time, amplitude * (time - start_time) * slope, 0)

plt.plot(time, signal)
plt.xlabel('Time')
plt.ylabel('Amplitude')
plt.title('Ramp Pulse Function')
plt.grid(True)
plt.show()
