The given figure shows the frequency spectrum of an amplitude modulated wave.
1. What are the names of (ωc – ωm) and (ωc + ωm).
2. What is the value of amplitude of (ωc – ωm) if modulation is µ?
3. What is the modulation index of AM, if the voltage amplitude of the carrier wave is 2kV and side band voltage amplitude is 200V.
