The carrier wave of a signal is given by C(t) = `3sin (8pit)`volt.
The modulating signal is a square wave as shown. Find its modulation index.

Explanation

To find the modulation index for the given carrier wave and modulating signal, we will follow these steps:

### Step 1: Identify the Carrier Wave Amplitude
The carrier wave is given by the equation:
\[ C(t) = 3 \sin(8 \pi t) \]
From this equation, we can see that the amplitude \( A_c \) of the carrier wave is:
\[ A_c = 3 \, \text{volts} \]
