一、基本原理: 波导电话是根据电磁感应原理,把音频电流经放大,采用调制方法加到高频信号上,成为调幅信号,放大后的调幅信号,通过发射天线,沿着良好导电性能的通讯线进行传播,这是一种特殊的波导,故称波导电话,类似无线电话。二、结构情况: 它由话筒,发射机,接收机,电源组成。 First, the basic principle: The waveguide phone is based on the principle of electromagnetic induction, the audio current amplified by modulation methods added to the high-frequency signals, an amplitude modulation signal, the amplified amplitude modulation signal through the transmitting antenna, along the good conductive properties of communication Line transmission, which is a special type of waveguide, so called waveguide telephone, similar to the wireless phone. Second, the structure of the situation: it consists of a microphone, transmitter, receiver, power supply.
