Question

In a superheterodyne receiver arrange the following components sequentially from input to output: A. Antenna B. Mixer C. IF amplifier D. Audio amplifier

• A. A, B, C, D
• B. A, D, B, C
• C. A, C, B, D
• D. D, C, B, A

Hint:

Receiver flow: Antenna → Mixer → IF amp → Audio amp.

Answer 1

The Correct Option is A

Concept: Superheterodyne receiver stages:
• Antenna → receives signal
• Mixer → converts to IF
• IF amplifier → amplifies IF signal
• Audio amplifier → final output

Step 1: Sequence \[ A \rightarrow B \rightarrow C \rightarrow D \] \[ \therefore \text{Correct answer is (A)} \]
