AM side refers to the range of frequencies that are used for broadcasting purposes during the AM (amplitude modulation) radio transmission. AM radio is a method of transmitting audio signals by varying the amplitude of the carrier wave. In this context, the "AM side" specifies a particular frequency range dedicated to AM broadcasting.
Typically, AM radio broadcasting covers a range of frequencies from 535 kHz (kilohertz) to 1605 kHz. The lower boundary, 535 kHz, is referred to as the low end or lower limit of the AM side, while the upper boundary, 1605 kHz, is known as the high end or upper limit of the AM side.
The AM side is divided into various channels, each separated by a specific frequency, such as 10 kHz or 9 kHz, depending on the region and regulations. These channels are assigned to different radio stations, enabling them to broadcast their programming content to listeners within their designated coverage area.
AM radio signals have the advantage of being able to travel long distances, especially during nighttime, due to their ability to be reflected and refracted by the Earth's atmosphere. This characteristic is primarily due to the lower frequencies used in AM transmission. However, the audio quality of AM signals is generally inferior to FM (frequency modulation) radio, as AM is more susceptible to noise, interference, and signal degradation.
Overall, the AM side encompasses the frequency range used for AM broadcasting, providing a means for radio stations to transmit their content over long distances using a carrier wave whose amplitude is modulated to reproduce audio signals.
