Calculation of modulation index using antenna current
The antenna current of the transmitter is 10A. Find the percentage of modulation when the antenna current increases to 10.4A.
a.) 32%
b.) 28.5%
c.) 64%
d.) 40%
Correct Answer: b) 28.5%
Explanation:
It= Ic √(1+ m2/2)
10.4= 10 √(1+ m2/2)
√ (1+ m2/2) = 1.04
Therefore m= 0.285
= 28.5%
