In 50% modulated signal, the carrier is suppressed for transmission. The saving in transmitted power would be—
-
- 88.9%
- 11.1%
- 72%
- 18%
- 88.9%
Correct Option: A
| % Power saving = | ×100 | |
| Total Power |
= | ×100 | |
| (1 + μ2/2) |
= | ×100 | |
| 2 + μ2 |
= | ×100 | |
| 2 + (0.5)2 |
(∴ μ = 50 % = 0.5)
= | ×100 = 88.88 % | |
| 2 + .25 |
Hence alternative (A) is the correct choice.
