On-off keying wikipedia
WebWikipedia WebOn–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 …

WebThe bandwidth of an on-off keyed signal is related to the data transmission rate as: = where is the necessary bandwidth in hertz, is the keying rate in signal changes per second (baud rate), and is a constant related to the expected radio propagation conditions; K=1 is difficult for a human ear to decode, K=3 or K=5 is used when fading or multipath propagation is … Web6 de mai. de 2024 · If you access the ports directly you can change the state of the output in a single clock cycle. On a 16MHz Arduino you can output an 8MHz square wave. The difficulty is going from "output square wave" to "send binary information". Riva July 12, 2013, 9:01am #3.
