What Is a Radio Transmitter?
A radio transmitter is a device that converts information like voice or music into radio waves for transmission.
There are several types of radio transmitters. Vacuum tube transmitters generate radio waves using vacuum tubes, while transistor transmitters use transistors. Additionally, digital transmitters employ digital modulation techniques to transmit voice or music with high audio quality.
Radio transmitters find applications in various fields, including broadcasting for radio stations, amateur radio for hobbyist communication, mobile phones for voice and data communication, and GPS for transmitting positioning information. They are characterized by their ability to transmit information and their wide range of uses.
