WebAns: The superheterodyne receiver offers superior sensitivity, frequency stability, and selectivity. Compared with the tuned radio frequency receiver (TRF) design, superhets offer better stability because a tuneable oscillator is more easily realized than a tunable amplifier. WebA Tuned Radio Frequency (TRF) Receiver is one of the simpler Radio types in existence. It is characterized by a low component count, reasonable sensitivity, and easy operation (it has only Tuning and Volume controls). The receiver consists of one (or several) stages of RF Amplification, a Detector, and Audio Amplifier.

WebAnswer (1 of 3): In a superheterodyne receiver the bandpass filtering of the unwanted signals is performed by the tunable RF filter and the Intermediate Frequency (IF) filter.
