Modulation ook

On-off keying ( OOK ) denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data at the presence or absence of a carrier . Les méthodes de modulation et démodulation des signaux sont, bien. The most basic modulation method is called On–Off Keying ( OOK ). Just shut off the RF carrier if there is a zero to transmit, and send a full-power carrier if there is. This paper discusses three popular modulation schemes in the presence of an interfering signal.

Par modulation OOK on retrouve, centrée sur la porteuse, la DSP en sinc2(fT) du signal modulateur (NRZ unipolaire). A good example is the bandwidth required to transmit data with OOK modulation versus that required with FSK modulation. In the case of FSK, using the . Both ASK and OOK modulation are ways to encode information and assemble them into radio signals to transmit, for example, wirelessly.
