ASK (Amplitude Shift Keying) is a type of digital modulation where the amplitude of a carrier wave is varied to represent digital data. In an ASK waveform, the carrier wave is present all the time, but its amplitude is changed to represent a binary 1 or 0.

FSK (Frequency Shift Keying) is a type of digital modulation where the frequency of a carrier wave is varied to represent digital data. In an FSK waveform, the carrier wave oscillates between two different frequencies, one for a binary 1 and the other for a binary 0.

PSK (Phase Shift Keying) is a type of digital modulation where the phase of a carrier wave is varied to represent digital data. In a PSK waveform, the carrier wave oscillates at a constant frequency, but its phase is changed to represent a binary 1 or 0.

It is worth mentioning that all of these waveforms are used to transmit digital data over a physical channel, they differ in the way they modulate the carrier wave to transmit the data.
