Question

Difference between trf and superheterodyne receiver

Answer 1

The image frequency band is an obstacle that presents itself in every superheterodyne receiver. When an RF input signal and an LO input signal enter a mixer, it generates an IF output signal at the mixer's output. ... Consequently, the task of filtering the image frequencies becomes much easier.

Answer 2

Hey friend here is your answer

The image frequency band is an obstacle that presents itself in every superheterodyne receiver .
When an rf input signal and an LO input signal enter a mixer, it generates an IF output signal at mixers output.
