This occurs by nonlinearly mixing the incoming RF signal with a local oscillator (LO) signal. Super-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

Engineering. 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 engineer Edwin Armstrong, S.Superheterodyne Architecture The choice of the IF frequency dictated by: If the IF is set too low, then we require a very high-Q image reject filter, which introduces more loss and therefore higher noise figure in the receiver (not to mention cost). If the IF is set too high, then subsequent stages consume more power (VGA and filters)19 дек. 2013 г. ...

In recent years, the rapid advance of analog-to-digital converter (ADC) sampling rates, the inclusion of embedded digital processing, and the integration of matched channels now offers options for the receiver architect that were not practical only a few years ago.
Download Solution PDF. For a superheterodyne receiver, the intermediate frequency is 15 MHz and the local oscillator frequency is 3.5 GHz. If the frequency of the received signal is greater than the local oscillator frequency, then the image frequency (in MHz) is __________. This question was previously asked in. The first components in the superheterodyne receiver system architecture are the antenna and TR switch. We replace the antenna block with the effective power reaching the switch. 1. The system uses the TR switch to switch between the transmitter and the receiver. The switch adds a loss of 1.3 dB to the system. …
