The carrier wave is represented by
`C(t) = 5 sin (10 pi t)` volt
A modulating signal is a square wave as shown in figure. Determine modulation index.

Explanation

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

### Step 1: Identify the amplitude of the carrier wave
The carrier wave is given by the equation:
\[ C(t) = 5 \sin(10 \pi t) \]
From this equation, we can see that the amplitude of the carrier wave \( A_C \) is:
\[ A_C = 5 \, \text{volts} \]
