7. Amplitude modulation issued for broadcasting because as compared to other system :
(a) It can provide the necessary bandwidth for high fidelity (b) It requires less transmitting power (c) It use avoids receiver complexity (d) It is more immune to noise
Answer
Answer : (c)
Explanation
Explanation : No answer description available for this question. Let us discuss.
Amplitude Modulation » Exercise - 19. For a given carrier wave maximum undistorted power is transmitted when value of modulation is : (a) 0 (b) 0.5 (c) 0.8 (d) 1.0
Amplitude Modulation » Exercise - 18. One can provide two or more voice circuits on the same carrier by using : (a) DSB-SC (b) SSB with pilot carrier (c) ISB systems (d) SSB-BC system
Amplitude Modulation » Exercise - 13. The percentage of modulation for 45 kHz deviation the FM broadcast band will be - (a) 30% (b) 40% (c) 60% (d) 90%
Amplitude Modulation » Exercise - 16. When signal amplitude is equal to the amplitude of the carrier, the percentage modulation factor will be : (a) 25 (b) 50 (c) 100 (d) 200
Amplitude Modulation » Exercise - 12. Maximum undistorted power output of a transmitter can be expected when its modulation is - (a) 50% (b) Between 50% and 90% (c) 100% (d) More than 100%
