GOOD OLD RADIO

Radio broadcasting has evolved tremendously over the years, while still holding its charm

- ANISHA GAKHAR

Who does not love an early morning drive with the radio blaring in the car—can relate, right? The good old radio is more than just the good old radio—it is a habit, a morning ritual, and a way to escape (and brace) the reality of what’s to come throughout the course of the day ahead.

Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves, and intended to reach a wide audience. In terrestrial radio broadcasting, the radio waves are broadcasted by a land-based radio station, while in satellite radio they are broadcasted by a satellite within the orbit of the earth. The signals are received by a receiver at the listener’s end. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM (Amplitude Modulation), FM radio stations transmit in FM (Frequency Modulation), which are older analog audio standards. New digital radio stations transmit in several digital audio standards: DAB (Digital Audio Broadcasting), HD radio, DRM (Digital Radio Mondiale).
