Radio communication
Radio communication is the transfer of high-frequency energy from the transmitter to the receiver without wires. Radio is a device that receives and transmits signals and programs by electromagnetic waves. Since the process o radio communication includes transmission and reception of signals, the necessary components of radio are a transmitter and a receiver.
The transmitter is a device that produces radio-frequency energy. The main parts of a transmitter are a high-frequency oscillator including an oscillatory circuit and one or a few amplifiers.
The receiver is a device that receives waves sent out by a transmitter. Radio receivers demodulate these waves which are then heard as speech, music or signals.
Electric oscillations produced in the antenna of the transmitter travel in all directions. Radio waves are the waves of very high frequency; they travel through the space at the speed of light. They differ from other wave forms only in frequency.
