A sinusoidal voltage is used to amplitude modulate a sinusoidal voltage of amplitude 1 KV. This results in the production of two side bands, each of amplitude 200 V. What is the modulation index ?A. 0.1B. 0.2C. 0.3D. 0.4 |

Answer» Correct Answer - D Amplitude of the carrier wave `(A_C)` = 1 KV = 1000 V Amplitude of each side band `=(muA_C)/2` `therefore 200=(muxx1000)/2 therefore mu = (200xx2)/1000=0.4` |
