AMringhääling
AMringhääling refers to Amplitude Modulation broadcasting, a method of transmitting audio signals. In AM radio, the amplitude of the radio wave is varied to encode the sound information. This is in contrast to Frequency Modulation (FM) broadcasting, where the frequency of the radio wave is altered. AM signals are generally simpler to transmit and receive, and can travel longer distances, especially at night when atmospheric conditions are more favorable. However, AM broadcasts are more susceptible to static and interference from electrical devices. The AM band typically covers frequencies from 530 kHz to 1710 kHz in North America, and similar ranges in other parts of the world. Historically, AM was the dominant technology for radio broadcasting, used for news, music, and talk programs. While FM has become more popular for music due to its higher fidelity and less susceptibility to static, AM radio continues to be used for various purposes, including talk radio, sports broadcasts, and emergency information. The technology behind AMringhääling involves modulating a carrier wave with the audio signal at the transmitter and then demodulating it at the receiver to extract the original sound.
