摘要:
摘要:应用BH1417F语音无线发送芯片和锁相环技术设计了一种无线发送电路。该电路由语音输入电路、语音放大电路、BH1417F 调理电路、高频功放及发射电路等组成,其特点是语音信号杂音小,接收机接收的音质清晰,可以预设不同的频点进行发射,信号接收的距离能够达到10m 以上。

Abstract: Utilizing the chip-BH1417F, which is a phonetic and wireless sending chip, and the phasiclocking technique, a type of wireless sending circuit is designed. This electrocircuit is composed of a sound input circuit, a modulation circuit, a high frequency OP circuit and a wireless emission circuit. The characteristics of this designed circuit are that the cacophony in sending sound signal is very small, the voice of receiver is clear, different frequency points can be set in advance and the transmit distance between the emitter and the receiver can exceed 10 meters. 2008 年第3 期孙加存,等:一种实用的调频发射电路设计 -
