What kind of media station did the broadcaster Turaga Janaki Rani work with for two decades, which is a station which uses the technology of radio waves to carry information by systematically modulating properties of electromagnetic energy waves transmitted through space?
Turaga Janaki Rani Turaga Janaki Rani (August 31, 1936-October 15, 2014) was a broadcaster, social activist and a writer worked with All India Radio for two decades. Popularly known as Radio Akkayya (Telugu: రేడియో అక్కయ్య Radio Sister).
Carrier wave In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information. This carrier wave usually has a much higher frequency than the input signal does. The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave (as in radio communication), or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing (as, for example, a cable television system). The term is also used for an unmodulated emission in the absence of any modulating signal.
