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… Web8 de out. de 2016 · Some of the major features in ooktools include: Binary string extraction from wave file recordings. Wave file cleanups to remove noise in On-off keying recordings. Graphing capabilities for wave files. General information extraction of wave files.
