9 Questions
What is the primary function of the Tuned RF amplifier stage?
To pass the desired RF signal and block other signals
The output of the Mixer stage contains which of the following signals?
The input RF signal, Local Oscillator signal, sum and difference of input and LO signals
Why is the Intermediate Frequency (IF) chosen to be much lower than the input signal frequency?
To make the IF amplifiers easier to design and achieve better selectivity
What is the function of the Detector stage?
To recover the original modulating signal from the Intermediate Frequency
In the Superheterodyne receiver, the output of which stage is fed to the audio amplifiers?
Detector
What is the purpose of the audio amplifiers in a Superheterodyne receiver?
