AM Signal Processing

AM signal processing involves converting audio or data signals into radio waves for transmission and then retrieving them accurately at the receiver. In amplitude modulation (AM), the strength (amplitude) of a carrier wave varies in direct proportion to the original message signal. The process includes modulating this carrier at the transmitter, transmitting the signal through the air, and then demodulating it at the receiver to recover the original audio or data. This technique allows the transmission of sound or information over long distances using radio frequencies, maintaining a balance between signal quality and bandwidth efficiency.
