频率调制
one of the main methods of radio broadcasting with a high sound quality
Frequency modulation (FM) is a method of transmitting radio signals by varying the frequency, or pitch, of the radio wave. In FM radio, the audio signal, such as music or speech, causes slight changes in the frequency of the carrier wave. This results in a clearer sound and less interference compared to other methods, like amplitude modulation (AM). FM is commonly used for music and high-quality radio broadcasts because it can transmit sound with better clarity and resistance to noise.
- Frequency modulation is commonly used in FM radio broadcasting to transmit high-fidelity sound over long distances.
频率调制通常用于FM无线电广播，以长距离传输高保真声音。
- Engineers prefer frequency modulation over amplitude modulation for its resistance to signal interference and noise.
工程师们更喜欢频率调制而不是幅度调制，因为它能抵抗信号干扰和噪音。
- The scientist explained how frequency modulation alters the frequency of the carrier wave to encode information.
科学家解释了频率调制如何改变载波的频率以编码信息。
- Many modern communication systems, including two-way radios and television broadcasts, rely on frequency modulation for clear signal transmission.
包括双向无线电和电视广播在内的许多现代通信系统都依赖于频率调制来实现清晰的信号传输。
- Understanding frequency modulation is essential for anyone studying electronics and communication engineering.
理解频率调制对于任何学习电子和通信工程的人来说都是必不可少的。
