RADIO RECEIVER Meaning and
Definition
-
A radio receiver is an electronic device designed to receive and amplify radio signals for the purpose of converting them into audible sounds. It is commonly known as a radio or radio set and is an essential component of radio communication systems.
The primary function of a radio receiver is to capture radio waves, which are electromagnetic waves of various frequencies, and extract the audio information embedded in them. The receiver uses an antenna to intercept these waves and feeds them into a series of electronic circuits. The antenna converts the electromagnetic signals into small electrical currents that represent the original signal. These electrical currents are then processed by various stages of amplification and filtering.
The amplified signal is then sent to a demodulator, a component that extracts the audio or data from the carrier wave. In the case of an AM (amplitude modulation) receiver, the demodulator recovers the audio signal by detecting changes in the amplitude of the received waveform. Alternatively, an FM (frequency modulation) receiver utilizes a different technique to decode the audio signal by examining the variations in frequency.
Once the audio signal is extracted, it is sent to an audio amplifier, which boosts its strength. Finally, the amplified audio signal is sent to a speaker or headphones, where it is converted back into sound waves that can be heard by the listener.

Etymology of RADIO RECEIVER
The word "radio" comes from the Latin word "radius", which means "ray" or "beam". It was first used by the French physicist Édouard Branly in 1897 to describe a device that detects and receives radio waves. The word "receiver" originated from the Old French word "recevoir", which means "to receive". The combination of "radio" and "receiver" is used to describe the device that receives and converts radio waves into audio signals, allowing the transmission of sound through electromagnetic waves.
