thanx burhan mam..i am thankful fr ur help.
i am actualy alsomconfuded abt working of fork and coupler…i dnt knw if they can be used for sme purpose like Dhiman sir has mentioned in previous comment.. i hope splitter wil gv good results instead of using fork..i hv gone through links also suggesting to use splitter instead of fork bcz of practical applications..
thnx agn
