如何创建具有随机周期的方波？

import random

def generate_square_wave(frequency_range, duration):
    # 生成随机周期
    period = random.randint(frequency_range[0], frequency_range[1])
    
    # 计算每个状态的持续时间
    high_duration = period // 2
    low_duration = period - high_duration
    
    # 生成方波
    wave = []
    total_duration = 0
    while total_duration < duration:
        wave += [1] * high_duration  # 高电平
        wave += [0] * low_duration  # 低电平
        total_duration += period
    
    return wave[:duration]  # 返回指定时长的方波

# 示例用法
frequency_range = (10, 20)  # 随机周期范围
duration = 100  # 方波时长
wave = generate_square_wave(frequency_range, duration)
print(wave)
