ASK modulation and demodulation for MATLAB

Amplitude shift keying is one of the digital modulation techniques. We can visualize this using Matlab

Amplitude Shift Keying ASK is a type of Amplitude Modulation which represents the binary data in the form of variations in the amplitude of a signal.

Any modulated signal has a high frequency carrier. The binary signal when ASK modulated, gives a zero value for Low input while it gives the carrier output for High input.

Below ASK signal , modulated and demodulated signals are given:
