a radio receiver that combines a locally generated frequency with the carrier frequency to produce a supersonic signal that is demodulated and amplified
The most widely used radio receiver in which the incoming signal is fed into a mixer and mixed with a signal from a local oscillator. The output produces an intermediate frequency that is amplified through an IF strip, detected by a diode and amplified in an audio amplifier.
A receiver that mixes the incoming signal with a locally generated signal (local oscillator) to produce a fixed, low intermediate frequency (IF) signal for amplification in the IF amplifiers.
The most widely used type of radio receiver, in which all incoming modulated radio-frequency signals are converted to a common intermediate-frequency or IF carrier value for additional amplification and selectivity prior to demodulation. The advantage to this method is that most of the radio's signal path has to be sensitive to only a narrow range of frequencies. The diagram below shows the basic elements of a single conversion superheterodyne receiver.
A type of receiver that uses a mixer to convert the RF echo to an IF signal for amplification.
Radio receiver that converts all radio frequencies to a fixed intermediate frequency to maximize gain and bandwidth before demodulation.
The superheterodyne receiver (or to give it its full name, the supersonic heterodyne receiver – often abbreviated superhet) is a design for radio receivers invented by Edwin Armstrong in 1918.
