WebMay 7, 2024 · The receiver basically is a tunable audio frequency amplifier with an envelope detector. It consists of a number of functional blocks, of which the main ones are the radio frequency (RF) amplifier, the band-pass filter, the second RF amplifier, the detector and associated low-pass filter, and output buffers. WebIn real life, the signal is received through an antenna. The first step is tuning of AM wave which is being done by the inductor and the capacitor. It provides selectivity, i.e. allows a wave of...

WebIn an amplitude modulation radio receiver a relatively narrow band filter is placed before the receiver detector and a relatively wide band filter is placed just prior to the IF amplifier … In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The term dates from the first three decades of radio (1888-1918). Unlike modern radio stations which transmit sound (an audio signal) on an uninterrupted carrier wave, early radio stations … See more Envelope detector One major technique is known as envelope detection. The simplest form of envelope detector is the diode detector that consists of a diode connected between the input and output of the circuit, … See more The phase-locked loop detector requires no frequency-selective LC network to accomplish demodulation. In this system, a voltage controlled oscillator (VCO) is phase locked by a feedback loop, which forces the VCO to follow the frequency variations of the … See more • Media related to Detectors (radio) at Wikimedia Commons • Simple block diagrams and descriptions of key circuits for FM transmitters and receivers: [1] See more AM detectors cannot demodulate FM and PM signals because both have a constant amplitude.
