INTRODUCTION
The transferof digital data over relativelylong distancesis generallyaccomplishedby sendingthe data in serialform thru a singlecommunicationschannel usingone of two generaltransmissiontechniques; asynchronousor synchronous.Synchronousdata transmissionrequiresthat a clock signal be transmittedwiththedata in orderto markto locationof the data bitsfor receiverA. specifiedclocktransition(eitherrisingor falling)marksthe startof eachdatabit intervalas shownin Figure1. In addition,special.synchronization datapatternsare addedto the startof the transmission inorderforthe receiverto locatethe firstbitof the message.
