WebKeywords—Power Line Communication, On Off Keying, Comparator, Filter, Equalizer I. INTRODUCTION Transmitter is composed of a square wave generator using a CMOS astable multi-vibrator. The square wave generator is used to generate a 125 KHz pulse signal. To implement the OOK modulation technique, the 0 and 1 signal is coupled 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… 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 … supplements to take while marathon training
