接收译码电路由红外接收放大器、音频译码电路和声控执行电路组成。接收红外二极管应采用与红外发射管配对的管，在收到红外光脉冲后，接收管D1的两极间电阻作与频率相应的变化，由光信号转化为电信号，经VT1和IC1放大-Received by the infrared receiver decoding circuit amplifier, the audio decoding circuit and voice-activated circuit implementation. Should be used to receive infrared diodes and infrared emission tube matching the tubes, infrared light pulses are received, the receiving tube D1 between the two poles and frequency of resistance for the corresponding changes in the electrical signals into optical signals, the VT1 and IC1 enlarge
