WebOOK stands for On Off Keying. OOK is modified version of ASK modulation. While in ASK modulation logic-0 is represented by lower amplitude and logic-1 is represented by higher amplitude; in OOK modulation there is no carrier during the transmission of logic zero. The carrier is transmitted during the transmission of logic one. WebSubject: Re: [Discuss-gnuradio] On Off Keying .
