What is 3 bit synchronous up counter JK flip-flop?

In the 3-bit synchronous counter, we have used three j-k flip-flops. As in the diagram, The J and K inputs of FF0 are connected to HIGH. The inputs J and K of FF1 are connected to the output of FF0, and the J and K inputs of FF2 are connected to the output of an AND gate, which is fed by the outputs of FF0 and FF1.

What is a mod 6?

The “mod 6” means that we are working only with the remainders of numbers after division by 6, and not really working with the integers at all. Note that this word “mod” is different from the modulus operator used in programming languages. Even though “4+3 = 1 mod 6” in English is true, “4+3 == 1%6” in C is false.

How to design a 3-bit counter?

Designing of such a counter is the same as designing a synchronous counter but the extra combinational logic for mode control input is required. 1. Decide the number and type of FF – Here we are performing 3 bit or mod-8 Up or Down counting, so 3 Flip Flops are required, which can count up to 2 3 -1 = 7. Here T Flip Flop is used.

How to design a Mod-6 counter?

Design of Mod-6 Counter: To design the Mod-6 synchronous counter, contain six counter states (that is, from 0 to 6). For this counter, the counter design table lists the three flip-flop and their states as 0 to 6 and the 6 inputs for the 3 flip-flops.

How many flip flops are required to make a 3-bit counter?

So, in this, we required to make 3 bit counter so the number of flip flops required is 3 [2 n where n is a number of bits]. Step 2: After that, we need to construct state table with excitation table.

How to do 3 bit up and down counting in t-Flop?

Here T Flip Flop is used. 2. Write excitation table of Flip Flop – 3. Decision for Mode control input M – When M=0 ,then the counter will perform up counting. When M=1 ,then the counter will perform down counting. 4. Draw the state transition diagram and circuit excitation table – State transition diagram for 3 bit up/down counting. 5.
