- Finding the maximum modulation factor for a two tone signal that can be employed without over modulation occurring

- Relevant Equations
- (Mt) = sqrt(m1^2+m2^2)

I'm stuck on this because v is a 2 tone signal, so it's not as simple as Am/Ac. The teacher said I will need to differentiate it and equate it to zero, which I thought made sense. Differentiating v gives me: [- m

I have seen another (looks easier) method where the Total Modulation Factor (Mt) = sqrt(m1^2+m2^2), where m1 = Am1/Ac and m2 = Am2/Ac. It does make sense, but I've spent a long time looking for where this, or something similar, is written down and haven't found anything so far.

Could anyone provide some help or point me towards some guidance please?

Thanks

*w*sin(w*t) - m*w*sin(2*w*t)], so there's still unknown variables. I don't know how I'm supposed to equate that to zero and find m when there are still variables that will not cancel.I have seen another (looks easier) method where the Total Modulation Factor (Mt) = sqrt(m1^2+m2^2), where m1 = Am1/Ac and m2 = Am2/Ac.
