补充资料:锁相环
锁相环 phase-locked loop 能使受控振荡器的频率和相位均与输入信号保持确定关系的闭环电子电路。锁相环由鉴相器、环路滤波器和压控振荡器组成。鉴相器用来鉴别输入信号Ui与输出信号Uo之间的相位差 ,并输出误差电压Ud 。Ud 中的噪声和干扰成分被低通性质的环路滤波器滤除 ,形成压控振荡器(VCO)的控制电压Uc。Uc作用于压控振荡器的结果是把它的输出振荡频率f。拉向环路输入信号频率fi ,当二者相等时,环路被锁定 ,称为入锁。维持锁定的直流控制电压由鉴相器提供,因此鉴相器的两个输入信号间留有一定的相位差。锁相环最初用于改善电视接收机的行同步和帧同步,以提高抗干扰能力。20世纪50年代后期随着空间技术的发展,锁相环用于对宇宙飞行目标的跟踪、遥测和遥控。60年代初随着数字通信系统的发展,锁相环应用愈广,例如为相干解调提取参考载波、建立位同步等。具有门限扩展能力的调频信号锁相鉴频器也是在60年代初发展起来的。在电子仪器方面,锁相环在频率合成器和相位计等仪器中起了重要作用。 |
