2. FM RADIO
Radio is the technology of signaling
and communicating using radio waves.[1][2][3] Radio waves
are electromagnetic waves of frequency between 30 hertz (Hz)
and 300 gigahertz (GHz). They are generated by an electronic
device called a transmitter connected to an antenna which
radiates the waves, and received by another antenna connected
to a radio receiver. Radio is very widely used in modern
technology, in radio communication, radar, radio
navigation, remote control, remote sensing, and other
applications
3. RADIO RECEIVER
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 informationcarried
by them to a usable form. It is used with an antenna. The antenna
intercepts 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 informationthrough demodulation.
