Final answer:
Frequency conversion in a super heterodyne receiver provides improved signal-to-noise ratio, reduced image frequency interference, and enhanced selectivity. Therefore, the correct answer is d) All of the above.
Step-by-step explanation:
Advantages of the frequency conversion process in a super heterodyne receiver:
- Improved signal-to-noise ratio: The frequency conversion process allows for the amplification of weak signals, resulting in a higher signal-to-noise ratio. This means that the desired signal can be extracted from the background noise more effectively.
- Reduced image frequency interference: By converting the incoming signal to a different frequency, the super heterodyne receiver can filter out the unwanted image frequency interference, resulting in a clearer reception.
- Enhanced selectivity: The frequency conversion process enables the receiver to have better selectivity by using filters to extract the desired frequency, allowing for better tuning and reducing interference from other frequencies.
Therefore, the correct answer is d) All of the above.
