用锁相式采样法抑制周期性干扰噪声
Cyclical Noise Restriction by Locking Sampling
-
摘要: 本文介绍一种对周期性干扰噪声有较强抑制能力的锁相式采样法,论述了该方法的理论 依据,并给出了实用锁相控制电路.该电路可以很方便地嵌入通常的数据采集系统.Abstract: In this Paper, the method of locking sampling for cyclical noise restriction is proposed. The idea of the method is discussed, and the circuit is also given. The circuit can be inserted into the usual data collecting system easily.
