How does a radio transceiver work? In radio communications, the transceiver can work inhalf-duplexorfull-duplexmode: Half-duplex transceivers.It can either transmit or receive but not both at the same time. This is because both the transmitter and receiver are connected to the same antenna usin...

A system known asCompatible QUAMis found in AM stereo radio applications. In this scenario, the different channels enable the required two channels for stereo to be carried by a single carrier. Digital versions of QAM are often calledquantized QAM. They are built into most radio communications s...
How Does a CB Radio Work? A citizens band (CB) radio is both a receiver and a transmitter. A radio receiver is an electronic device that receives audio signals through an antenna, then amplifies and sends the sound to speakers. A transmitter does the opposite: it takes microphone (a rever...
An AM radio transmitter uses an oscillator to create the carrier wave for the station, while an AM radio receiver uses a special form of oscillator called a resonator to tune into a station. There are even oscillators in computers, metal detectors and stun guns. To better understand how ...

A machine like a player-piano detector (red) reads the pattern of holes and sends corresponding electrical signals to a radio tuning system (green) that picks one of 88 possible frequencies on which to beam signals out to the receiver using a standard radio transmitter (orange). The receiver...
No, FM Transmitter Apps Don't Work Unfortunately, you need hardware to transmit any kind of FM signal, which almost all phones don't have. While you might remember that some old feature phones and even modern smartphones have a built-in FM radio, it is not the same as FM transmission....
