.but in case of self starting counter since we are always able to enter into the counting loop (which here corresponds to a valid state), so in this case howcum this counter becomes lockout counter?

yeah i analyze it in a wrong way

you're right

forming a loop using unused states but still we are able to enter into the counting loop from there .. Then in this case is it a lockout counter?

but this case is wrong

can you draw any counters like this ?? In which unused states forming loop but still we are able to enter into the counting loop from there :p ??

ok i got it :P I was  trying to deduce all the possible cases :P

Answer 1

i have a doubt... design a jk counter that goes through state 2,4,5,7,2,4....and modify the circuit whenever it goes to any invalid state it comes back to 2.designing is done how to do the modification?? what do we do now??
