So, the following procedure needs to be followed for the designing of synchronous counters for any mod-N counter: Step 1: Determine the number of flip-flops. arrow_forward. 4-bit-counter-using-d-flip-flop-verilog-code 1/3 Downloaded from magazine.compassion.com on November 11, 2022 by Suny e Robertson . #digitalelectronics #counters in this video i have discussed how we can design mod-6 synchronous up counter using jk flip flop mod 6 counter also known as divide by 6 counter playlist. The basic principle for constructing a synchronous counter can therefore be stated as follows Each FF should have its J and K inputs connected so that they are HIGH only when the outputs of all lower-order FFs are in the HIGH state. Transcribed image text: PREWORK: Design a mod-6 synchronous up-counter using JK flip-flops. Here, MOD number is equal to 5. Design mod -3 up counter using J-k flip flop. This is shown in the following Figure of a 4-bit up-down counter using T flip-flops. In the case of synchronous FFs, all the flip flops are triggered simultaneously by an external clock pulse. Choose the type of flip flop. AIM of the Experiment: Designing of Mod-6 synchronous counter using J-k flip flop Apparatus Used: Proteus 8.11 Professional Excitation table of T FF. Electronic counters: An electronic counter is a sequential logic . All the JK flip-flops are configured to toggle their state on a downward transition of their clock input, and the output of each flip-flop is fed into the next flip-flop's clock. (Show the state diagram, state table, state equations, flip-flop input equations, and the logic diagram.) Find the number of flip flops using 2n N, where N is the number of states and n is the number of flip flops. In certain applications, a counter must be able to count both up and down. Design steps of asynchronous counter. Using D flip-flops and the state equation method. Step 1 : Decision for number of flip-flops - Example : If we are designing mod N counter and n number of flip-flops are required then n can be found out by this equation. Since this is to be a fully synchronous counter, DO NOT use the asynchronous CLR' input to reset the counter. . From the above diagram, it is clear that the minimum number of flip-flops (n) required to design a mod-6 counter is, M<2 n 4<2 n or n=3. i.e., M = 5 Therefore, 5 2N => N = 3 Therefore, to design a MOD 5 Counter, 3 flip-flops would be required. diagram, state table, state equations, flip-flop input equations, Therefore number of FF required is 4 for Mod-10 counter. As the input clock pulses are applied to all the Flip-flops in a synchronous Design a mod-6 UP/DOWN counter: A) Using JK flip-flops and the Draw the excitation table of the selected flip flop and determine the excitation table for the counter. Find the number of flip flops using 2 n N, where N is the number of states and n is the number of flip flops. Since a mod 6 Johnson counter can count up to 6 states, 3 flip flops will be required. An up-down counter is a combination of an up-counter and a down-counter. and put to it 1,2 negated, 4 and 8 (refering to the flip flop output) and such and you set it to the reset of all the JK flip flops. mod 6 synchronous.txt - AIM of the Experiment: Designing of Mod-6 synchronous counter using J-k flip flop Apparatus Used: Proteus 8.11 Professional. 1st step is tabulating the present state - next state table In up counter from 000 to 111. so the we write excitation table for. Steps involve in design are : Step 1 : Decision for Mode control input -. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators . Use K-map to derive the flip flop reset input functions. Using D flip-flops and the state equation method. State Diagram : The circuit design is such that the counter counts from 0 to 5, and then on the 6th count it automatically resets to begin the count again. A combinational circuit is required between each pair of flip-flop to decide whether to do up or do down counting. Here is the logic diagram of 4-bit ( MOD-16) synchronous counter using J-K flip-flops (figure 1 (c)). (Show the state The preset and clear ends of the flip-flops are not inverted) .
