In this part, by looking to this figure that we have, this is to determine, or this would be the sinusoidally modulated dsblc.
00:13
And based on this one, for our step two, we need to use this formula that is the modulation index.
00:21
So the modulation index that would be equal to 90 minus 40 over 2 over 90 plus 40 over 2.
00:43
This would be equal to 0 .38.
00:47
The modulating signal, we have the modulating signal amplitude that is 90 minus 4 .4.
01:01
Divided by 2 is 25 voltage.
01:06
So we have the carrier signal amplitude.
01:15
So that would be ac is equals to 90 plus 40 divided by 2.
01:21
That would be 65.
01:23
If carrier frequency is f subscript c and the modulating frequency, so we have the modulating frequency.
01:33
So we have the modulating...
