What does fm/am mean in a car?
2 Answers
fm/am refers to the radio function in a car. FM stands for frequency modulation broadcasting, while AM refers to amplitude modulation medium-wave broadcasting. After pressing the corresponding button, you can listen to the radio in the respective frequency band. Generally, FM is more commonly used. FM is the frequency modulation broadcasting of the radio, and the AM band refers to medium-wave broadcasting, while FM is short-wave. Below is a related introduction to car audio equipment: 1. Audio source: The component that can decode software and multimedia is called the audio source. 2. Power amplification component: The sound signal intensity controlled by the pre-stage is mostly only a few volts, which is not enough to drive the unit. Therefore, the signal must be 'boosted' to make it stronger, allowing it to be calculated in watts (W). The component that strengthens the signal into power output is called the power amplifier, commonly known as the amp.
I usually enjoy listening to the radio to relax while driving to and from work. FM (Frequency Modulation) radio on the car offers clear sound quality, making it great for listening to songs or music programs, especially when driving in the city where the signal is stable. AM (Amplitude Modulation) radio might have some static noise, but it has a wider signal coverage, so you can still catch news or traffic updates even when driving long distances to mountainous areas. These two buttons are usually separate on the radio panel, and you can switch between them with a press. I recommend using FM more often and switching to AM if the signal gets weak. Remember to check the antenna—sometimes if it's loose, it can affect reception. Developing this habit can make driving more convenient.
