Q- Design the ripple counter whose output sequence is represented by the following state diagram. Ans: As we can see that it is a down counter so we’ll be using Q bar of all flip-flops as clock to next flip-flops (negative edged FFs). We draw the table as Q2 Q1 Q0 OUTPUT 0 0 0 0 […]

Q: MOD 6 Counter
Q- Can we design a MOD-6 counter using the above method? Ans: We firstly draw the state diagram And now we draw the table to represent the desired output of the combinational circuit to reset FFs as: Q2 Q1 Q0 OUTPUT 0 0 0 1 0 0 1 1 0 1 0 1 0 1 […]
USING K-MAPS to design counter
Q- Design MOD-3 ripple counter using (a) Observing outputs (b) K-maps to design the circuit. Ans: (a)We can design the MOD 3 counter using 2 FFs as 3 is less than 4 i.e. 22 and greater than 2. We can see directly that as we have to reset the counter only after 2 i.e. when output is […]
