It is usedwith an antenna. The antenna intercepts radio waves (electromagnetic waves) andconverts them to tiny alternating currents which are applied to the receiver,and the receiver extracts the desired information. The receiver uses electronicfilters to separate the desired radio frequency signal from all the othersignals picked up by the antenna, an electronic amplifier to increase the powerof the signal for further processing, and finally recovers the desiredinformation through demodulation.   The information produced by the receivermay be in the form of sound (an audio signal), images (a video signal) or data(a digital signal).[1] A radio receiver may be a separate piece of electronicequipment, or an electronic circuit within another device. Devices that containradio receivers include television sets, radar equipment, two-way radios, cellphones, wireless computer networks, GPS navigation devices, satellite dishes,radio telescopes, bluetooth enabled devices, garage door openers, and babymon
