Hi
your system has 4 state, because u have 2 bit.
(00)^2 = (00)
(01)^2 = (01)
(10)^2 = (100) u can truncate it to (00)
(11)^2 = (1001) u can truncate it to (01)
u can do something else instead of truncation depend on your sytem and your defenition of power 2 in fixed point binary
however I'm not electronics guru and I still don't understand how this can relate to my system. Do I have to use any chips if so which? or this is straight math? Once again thanks for your help!!!
