AM/FM system is a new information management system for production operation unit, which is developed on the basis of geographic information System (GIS) and according to the needs of equipment engineering management and production technology management. In many cases, AM/FM/GIS is also used to represent AM/FM systems.
Signal transmission, transmission mode
The signal is transmitted as if you were making a sound. The transmitting device is mainly composed of resistors and inductors, forming a resonant circuit to generate the desired carrier frequency. The transmitter transmits the modulated signal through the antenna into the air for the receiving device to receive. It's like when you shout through a loudspeaker so that your distant friends can hear you.
Reception of signal
Once you get the signal, it's like when you hear a friend Shouting and you need to understand what he means. First, the audio information in the high-frequency carrier signal needs to be extracted by demodulator. The process of demodulation involves filtering to remove the high-frequency components, leaving only the low-frequency audio signal. The demodulation methods of AM signal and FM signal are different. AM signal is demodulated by envelope detector, FM signal is demodulated by frequency discriminator.
