补充资料：鉴相器
| 鉴相器 phase detector 使输出电压与两个输入信号之间的相位差有确定关系的电路。表示其间关系的函数称为鉴相特性。鉴相器是锁相环的基本部件之一，也用于调频和调相信号的解调。常见的鉴相特性有余弦型、锯齿型与三角型等。鉴相器可以分为模拟鉴相器和数字鉴相器两种。二极管平衡鉴相器是一种模拟鉴相器。两个输入的正弦信号的和与差分别加于检波二极管 ，检波后的电位差即为鉴相器的输出电压。其鉴相特性通常为余弦型的。鉴频鉴相器是一种数字鉴相器。两个输入信号是脉冲序列，其前沿（或后沿）分别代表各自的相位。比较这两个脉冲序列的频率和相位即可得到与相位差有关的输出 。这种鉴相器的鉴相特性为锯齿形。因它兼具鉴频作用，故称鉴频鉴相器。 |
