大家好，谁能指导我如何产生50％占空比的方波从[color]软件1Hz至1MHz的。[/彩色]有任何单一的IC芯片内置产生方波。

这是可以做到与CMOS的555定时器的版本.. [网址] http://www.national.com/ds/LM/LMC555.pdf [/网址]这里是一个方波发生器例如基于标准版本（应该高达100kHz）：[网址] http://talkingelectronics.com/html/SquareWaveOsc.html [/网址]首先，产生2Hz至2MHz，然后作出完美的50％占空比除以二它使用触发器.. [网址] http://www.play-hookey.com/digital/frequency_dividers.html [/网址] IanP：ð

嗨，你也可以使用单片机定时器来划分微观主体振荡器所需的频率容易做到的16位STM32的定时器 - 只需锁定锁相环及设置定时器寄存器使用统筹处的信号输出所有最优秀的波比[我] [color]软件的单片机专家[/乙] [/彩色] [/我]

这样做的人有ModelSim的代码生成的3个输入方波（时钟，范围，控制）为1兆赫的时钟范围为0 / 1（千赫/赫兹）控制的3位时钟乘法器
