Question

If the initial stage of mod-11 counter is 0110, then what will be the counting sequence for next 24 clock pulses?

What will be counting sequence for the next 17 clock pulses if the counter is mod-16 down counter and the initial value is 1110?

Answer 1

MOD-N counter indicates the number of states in counting sequences. 

• MOD-11 (synchronous) counter has a count from $0-10$ states, that is $0,1,2,3,4,5,6,7,8,9,10$.The initial state is $(0110)_2=6$ so after $24$ clock pluses it will be reach to the $(1000)_2=8$ state.
• MOD 16 down counter starts counting from $15,14,13,12,11…….0$. The initial state is $(1110)_2=14$, after $16$ clock pluses it will again reach to the $1110$ state. so in 17th clock pulse it will reach to the $(1101)_2=13$ state. 

Answer 2

(1) ANS-1000

             BEZ OF MOD -11 COUNTER SEQUENCE IS

                          1->2->3->..................10->1    

                         WHEN START FROM 0110 AFTER 22 CLOCK IT REACH AT THAT STATE THEN I HV REMAINING 2 CLOCK THEN FORWARD TWO STATE THEN WE GET 1000.

(2) ANS-1101

how it will decide that it's up/down counter, if not given in que??
