radio receiver

Also known as receiver, radio

radio device for receiving radio waves and converting them to a useful signal

AI overview

A radio receiver is a device that picks up radio waves traveling through the air and converts them into signals you can actually use, like sound from a speaker or images on a screen. It matters because it's the technology that lets you listen to music, news, and other broadcasts without needing a physical connection to the source.

Encyclopedic overview

A modern communications receiver, used in two-way radio communication stations to talk with remote locations by shortwave radio. A clock radio, a bedside broadcast AM and FM radio receiver combined with an alarm clock. The clock can be set to turn on the radio in the morning, to wake the owner with audio from a broadcast radio station.

In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna responds to radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation.
