RADIO SIGNAL Meaning and
Definition
-
A radio signal refers to an electromagnetic wave that carries information or specifically designed for wireless communication through the air via radio frequencies. It is a form of energy propagation characterized by periodic oscillations of electric and magnetic fields that extend uniformly outward from a transmitting antenna. These signals are utilized in various applications, including broadcasting, telecommunications, navigation, and wireless networking, amongst others.
Radio signals typically fall within the radio frequency portion of the electromagnetic spectrum, encompassing the range from around 30 kHz (kilohertz) to 300 GHz (gigahertz). They can be analog or digital in nature, depending on the specific information encoded within them. Analog signals continuously vary in amplitude and frequency, whereas digital signals are discrete and quantized, representing information through binary code.
Transmitting radio signals involve modulating the carrier wave by superimposing the desired information, such as audio, video, or data, onto the signal. This modulation process often occurs through methods like amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM). Once the modulated signals are emitted by the transmitting antenna, they propagate through space and can be captured by a receiver where they are demodulated, extracting the information they carry.
Overall, radio signals are the vital means for wireless communication and play a pivotal role in connecting people, devices, and transmitting information reliably over short or long distances.

Etymology of RADIO SIGNAL
The word "radio" originates from the ancient Greek word "radius", meaning "a beam of light" or "a spoke of a wheel". The term was first applied to electromagnetic radiation in the late 19th century by renowned physicist and inventor, Nikola Tesla. "Signal", on the other hand, comes from the Latin word "signum", meaning "a sign" or "a mark". Therefore, the combination of "radio" and "signal" refers to the electromagnetic waves or beams of light used to transmit information or communicate wirelessly.
