Webb21 feb. 2024 · On-off keying (OOK) is a modulation scheme that consists of keying a sinusoidal carrier signal on and off with a unipolar binary signal. OOK is equivalent to two-level amplitude-shift keying (ASK). Unipolar Binary Baseband Signal Resulting OOK Modulated Signal Was this information helpful?

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…
