A 4-bit binary ripple counter uses flip-flops with a propagation delay time of 25 ns each. The maximum possible time required for change of the state will be—
-
- 25 ns
- 50 ns
- 75 ns
- 100 ns
- 25 ns
Correct Option: D
Given no. of flip-flops (i.e., no. of bits) = 4 Propagation delay of each flip-flop, tpd = 25 ns. The maximum possible time required for change of the state = 4 × tpd = 4 × 25 = 100 ns.
