Most bandwidth efficient transmission of voice signals iii. SSB-SC d. Simplest Receiver Circuit iv. FM
a-iv, b-ii, c-iii, d-i
To solve this matching problem, we need to understand the characteristics of different modulation schemes listed in List-II and their applications as described in List-I.
Let's analyze each option:
- Power efficient transmission of signals: - Frequency Modulation (FM) is generally known for being power-efficient as it keeps the amplitude constant and only changes the frequency of the carrier wave. Hence, the correct match is FM for power efficiency. - Correct match: a-iv.
- Bandwidth efficient transmission of signals with significant DC signals: - Vestigial Sideband Modulation (VSB) is often used for television broadcasting because it conserves bandwidth effectively while allowing the transmission of DC and low-frequency signals. - Correct match: b-ii.
- Most bandwidth efficient transmission of voice signals: - Single Sideband Suppressed Carrier (SSB-SC) is extremely bandwidth-efficient compared to other analog modulation schemes, as it transmits only one sideband and does not waste power on an unneeded carrier. - Correct match: c-iii.
- Simplest Receiver Circuit: - Amplitude Modulation (AM) requires the simplest receiver circuit because it needs only a basic diode for demodulation. - Correct match: d-i.
Based on the explanation above, the correct combination of matches is a-iv, b-ii, c-iii, d-i, which corresponds to the given correct answer.
