JJ, 500 / 1000 = 50% 'Doc |

It takes 50 watts of audio to 100% modulate 100 watts of carrier. This is assuming high level modulation where the audio is applied to the output stage. At 100% modulation power is increased 1.5 times the unmodulated carrier power. So for 100 watts with 100% modulation, the output would be 150 watts, with 100 watts in the carrier and 25 watts in each sideband. Get a book and look it up. |
