The Transmitter: The Heart of Transmission
The transmitter is the device that converts audio or video signals into radio frequency (RF) signals. It amplifies the signal and broadcasts it through an antenna. The power of the transmitter determines the reach of the signal, allowing it to broadcast over a greater range.
The Receiver: Capturing the Signal
The receiver is the device that receives the transmitted signal. It captures the signal and converts it back into audio or video. Receivers use an antenna to collect the RF signals.
The Frequency: Navigating the Airwaves
Radio frequencies are specific ranges of electromagnetic waves that are used to transmit radio signals. Each radio station and TV channel is assigned a specific frequency to prevent interference. The Federal Communications Commission (FCC) regulates the allocation of frequencies in many countries.
The Signal: The Foundation of Communication
A broadcast signal is the method of transmitting information over the airwaves. Signals can vary, using formats such as AM, FM, and digital transmissions.
