Low Frequency Transmission refers to the process of sending signals at low frequencies, typically below 300 kHz. This method is often used in radio communications, navigation systems, and some types of broadcasting. Low frequency signals can travel long distances and penetrate through obstacles like buildings and the ground, making them useful for various applications. One common use of low frequency transmission is in AM radio broadcasting, where stations transmit signals that can be received over vast areas. Additionally, it plays a role in submarine communication, allowing messages to be sent underwater where higher frequencies would be absorbed quickly.
