无线监听系统的工作原理是发射机中电流强弱的改变会产生无线电波。通过编码器调制将信息加载到无线电波上。当电波通过空间传播到达接收机,电波引起的电磁场变化又会在导体中产生电流。通过解码器解调将信息从电流变化中提取出来。达到了信息传输 Wireless monitoring system works is the transmitter current changes in the intensity will produce radio waves. The information is loaded onto the radio waves by the encoder modulation. When the radio wave reaches the receiver through the space, the electromagnetic field caused by the radio wave will produce a current in the conductor. The information is extracted from the current changes by the decoder demodulation. Reached the information transmission
