There are two types of AM signals: onoff keying (OOK) and amplitude shift keying (ASK). In Figure 1a, the carrier amplitude is shifted between two amplitude levels to produce ASK. In Figure 1b, the binary signal turns the carrier off and on to create OOK.

The shape, after bandlimiting, … On–off keying (OOK) denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as the presence or absence of a carrier wave. In its simplest form, the presence of a carrier for a specific duration represents a binary one, while its absence for the same duration represents a binary zero. Some more sophisticated schemes vary these durations to conve…
