Analog Radio
Analog radio refers to the traditional method of transmitting radio signals using analog modulation techniques. In this method, the audio signal is superimposed onto a carrier wave by varying its amplitude or frequency. The resulting modulated signal is then transmitted through the air using an antenna. Analog radio signals are susceptible to noise and interference, which can cause distortion and reduce the quality of the audio signal. However, analog radio has been widely used for decades and is still in use today, particularly in areas where digital radio coverage is limited or unavailable.
