摘要:
目前LED大屏信号分为网线传输的有线信号和GPRS、3G、4G等无线方式传播的无线信号。采用BH1417F调频立体声发射集成芯片制作发射机,数字FM调频机作为接收机,通过GP天线实现音频信号的传输。
Abstract:
Current LED large screen signals include cable signals transmitted through cable, and wireless signals transmitted wirelessly, such as GPRS, 3G, 4G. This design uses the BH1417F FM stereo transmitter integrated chip as the transmitter, applies digital FM FM headphones as the receiver, and achieves the transmission of audio signals through GP antenna.
