摘要:The optical fiber identifier need to identify varies of modulated signals. In the paper, integrated PLL Decoder LM567 and Analog Multiplexers switches CD4051 were used to constitute multi-frequency decoding circuit. MCU selects CD4051's different channels to identify modulated signals including 270HZ, 330HZ, 1kHz and 2kHz. The performance of the decoding circuit is good in practical application.
