No need to panic. Anyt problems with this I will detect. The more you go over something, then you find the questions. At the moment it's the modulation index I am scrutinizing. The example itself is simple. If there's a maximum carrier frequency deviation of 3000 cycles yet the modulating frequency is 1000, the index is 3. Mathematically you can use the index to calculate the carrier deviation. I tried to convert the books frequencies into megacycles to get carrier 29.5 Meg, modulating frequency 2000 Kilocycles and 29.506 (6000 K deviation quoted + cycle. So if I have got this right the modulating index is 3 because 2000 into 6000 goes 3 times.
I still have an issue with the modulation index. There is a graph that shows the indexes in fractions.
This may take a few days...
