**Step-by-Step Text Solution:** 1. **Definition of Modulation**: Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. 2. **Understanding Carrier Signal**: A carrier signal is characterized by a steady waveform, which means it maintains a constant height (amplitude) and frequency over time. 3. **Process of Modulation**: In modulation, information (which could be audio, video, or data) is superimposed onto the carrier signal. This allows the information to be transmitted over long distances without significant loss. ...
