amplitude shift keying[′am·plə‚tüd ¦shift ‚kē·iŋ]
A method of transmitting binary coded messages in which a sinusoidal carrier is pulsed so that one of the binary states is represented by the presence of the carrier while the other is represented by its absence. Abbreviated ASK.

The solutions used simple modulation techniques like amplitude-shift keying
(ASK) or frequency-shift keying (FSK).
Simple modulators for schemes such as amplitude-shift keying
(ASK), binary phase-shift keying (BPSK) and frequency-shift keying (FSK) can be designed using a wide range of techniques.
The basic possibilities are amplitude-shift keying
(ASKe, phase-shift keying (PSK) and frequency-shift keying (FSK).
The device operates over a supply voltage range of 2.7 to 5 V and can be configured for BPSK, amplitude-shift keying
or FM data modulation.
