A carrier wave of peak voltage 12 V is used to transmit a message signal. What should be the peak voltage of the modulating signal in order to have a modulation intex of 75 % ?

Explanation

To solve the problem, we need to find the peak voltage of the modulating signal (Am) given the peak voltage of the carrier wave (Ac) and the modulation index (µ).

### Step-by-Step Solution:

1. **Identify the given values**:
- Peak voltage of the carrier wave (Ac) = 12 V
- Modulation index (µ) = 75% = 0.75 (convert percentage to decimal)
