"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… " - Shaped on-off keying

Webb4 juli 2011 · fcfusion said: You're demodulating and filtering using RC components, so it's natural your circuit presents delays t = RC; Solution: use smaller RC values. This will inevitably increase the filter's cut off frequency, lowering the ripple attenuation. Therefore you should also increase the filter's order. Webb15 maj 2024 · On-Off Keying (OOK) is equivalent to AM modulation of the carrier with the data bit-stream with a 100 % modulation index. As a result the entire spectrum of the bit stream is up-converted to the carrier frequency of the OOK modulator.
