What does FM mean in a car?
1 Answers
FM in a car refers to the frequency modulation band in the car audio system's radio function. It represents the technology used by radio stations to transmit signals and the standard received by the receiving equipment (radio). After pressing the button, you can listen to the radio on the corresponding band, which represents the technology used by radio stations to transmit signals and the standard received by the receiving equipment (radio). For example, in wireless TV signals, the image uses amplitude modulation, while the sound uses frequency modulation. An FM radio receives FM station signals through an antenna, which are then tuned, amplified, and demodulated by the circuit to separate the audio signal. This signal is then amplified at low frequencies and output through the speaker to produce sound. FM components: The car audio system consists of five parts: the antenna, receiving device, speaker correction, audible frequency amplification, and speaker system. FM function: The antenna is used to receive the broadcast waves transmitted by radio stations and sends them to the radio frequency modulation device via a high-frequency cable. The receiving device selectively picks up the high-frequency electromagnetic waves transmitted by the station and demodulates them into audio electrical signals.
