The initial state of MOD-16 down counter is 0110. What state will it be after 37 clock pulses?
Answer: Option
Explanation:
A mod-16 counter goes through 16 states in one cycle of 16 Pulses.
It complete 2 cycles in 32 Pulses.
In the rest 5 Pulses, it moves down from 0110 = 610 - 510 = 110 or (001)2 .

For MOD 16, it has 16 clock pulses. As counter counts down starting from '6' = 0110 from 0th clock pulse. When it reaches to 16th clock pulse its going to be 7, 20th clock pulse is 3, 31th clock pulse is 7. Therefore on counting down it reaches 1 in 37th clock pulse.
(6= (1st clk pulse) , 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4,
3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1= (37th clk pulse)).
(6= (1st clk pulse) , 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4,
3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1= (37th clk pulse)).
