Super heterodyne receivers
WebThe superheterodyne receiver has several advantages over previous receiver designs. One advantage is easier tuning; only the RF filter and the LO are tuned by the operator; the fixed-frequency IF is tuned ("aligned") at the factory and is not adjusted. WebSuper-Heterodyne AM Receiver 22 Envelope Detector • The envelope detector recovers the original m(t) modulation and a DC voltage that is proportional to the received signal carrier amplitude A c. • The DC voltage is used to automatically adjust the gain of the IF amplifier in a control loop (AGC- automatic gain control). This maintains a

A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency. It was long believed to have been invented by US … See more Heterodyne Early Morse code radio broadcasts were produced using an alternator connected to a spark gap. The output signal was at a carrier frequency defined by the physical construction of the … See more Microprocessor technology allows replacing the superheterodyne receiver design by a software-defined radio architecture, where the IF processing after the initial IF filter is … See more First detector, second detector The mixer tube or transistor is sometimes called the first detector, while the demodulator that extracts the modulation from the IF signal is called the second detector. In a dual-conversion superhet there are two mixers, so the demodulator … See more The diagram at right shows the block diagram of a typical single-conversion superheterodyne receiver.
