Question 94

---

94. What does the following logic diagram represent ?

Flip-Flop Logic diagram

Options:

1. 1. Synchronous Counter
2. 2. Ripple Counter
3. 3. Combinational Circuit
4. 4. Mod 2 Counter

Answer : 2. Ripple Counter

Explanation Question 94

Ripple Counter : Ripple counter is an Asynchronous counter. It got its name because the clock pulse ripples through the circuit. An n-MOD ripple counter contains n number of flip-flops and the circuit can count up to 2 ⁿ values before it resets itself to the initial value.

Given Flip-Flop Logic diagram represents the Ripple counter.

So, option 2 is correct answer
