Amplitude-shift keying

Amplitude-shift keying (ASK) is a digital modulation technique used in telecommunications. It conveys digital information through variations in the amplitude of a carrier wave. In ASK, the amplitude of the carrier signal is changed to represent binary data, typically 0s and 1s. ### Key Features of Amplitude-shift Keying: 1. **Modulation Process**: In ASK, different amplitudes of the carrier signal are used to represent different binary states.
