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… WebAbstract: This paper compares the efficiency of on-off Keying (OOK) modulation formats non-return-to-zero (NRZ) and return-to-zero (RZ) in both electrical and optical chromatic … Web6.2 ON–OFF KEYING In OOK encoding, the optical light is pulsed on or off during each bit time, as shown in Figure 6.2 a. Each “1” bit is encoded into an optical pulse and each “0” bit is encoded into an off (no field) bit. Clearly, the maximum source bit rate is directly related to the rate at which the source can be switched on and off. norfolk sea fishing reports 2022
