Although the superheterodyne receiver is the undisputed performance champion
and the world as we know it could not exist without superheterodyne receivers,
they are far from perfect. Therefore, we will first discuss the primary shortcoming ...
The chief objective of the superheterodyne receiver is to produce a constant
intermediate frequency at which amplification efficiency as well as uniform
selectivity and uniform sensitivity can be attained. The amplified modulated
signal at a ...

The Electronics Handbook, Second Edition
Often it is desired that the receiver output be a replica of the modulating signal
that was present at the transmitter input. There are two main classes of receivers:
the tuned radio frequency (TRF) receiver and the superheterodyne receiver.

RF & Wireless Technologies
The superheterodyne receiver is the most common configuration for radio
communication. Its basic principle of operation is the transfer of all received
channels to an intermediate frequency band where the weak input signal is
amplified before ...
