补充资料:分频器
分频器 frequency divider 使输出信号频率为输入信号频率整数分之一的电子电路。在许多电子设备中如电子钟、频率合成器等,需要各种不同频率的信号协同工作,常用的方法是以稳定度高的晶体振荡器为主振源,通过变换得到所需要的各种频率成分,分频器是一种主要变换手段。早期的分频器多为正弦分频器,随着数字集成电路的发展,脉冲分频器(又称数字分频器)逐渐取代了正弦分频器,即使在输入输出信号均为正弦波时也往往采用模数转换-数字分频-数模转换的方法来实现分频。正弦分频器除在输入信噪比低和频率极高的场合已很少使用 。对于任何一个 N 次分频器,在输入信号不变的情况下,输出信号可以有N 种间隔为2π/N 的相位。这种现象是分频作用所固有的,与分频器的具体电路无关,称为分频器输出相位多值性。脉冲分频器有很宽的工作频带,低频端实际上没有限制,高端极限频率主要决定于使用的器件,但也与电路有关系。 |
