How does a CB Radio Work?
CB radios operate on the principle of amplitude modulation (AM). They utilize the electromagnetic spectrum to transmit and receive signals. CB radios operate on specific frequencies within the 27 MHz band, allowing users to communicate over short distances. The voice messages are modulated onto the carrier wave by varying the amplitude, and the receiver demodulates the signal to reproduce the original voice message. CB radios typically have a fixed set of 40 channels, each with a designated frequency, allowing multiple users to communicate simultaneously.
