3 Bit Up Down Counter Using T Flip Flop

3 Bit Up Down Counter Using T Flip Flop. Up and down counter using 74ls192 and 7447. I made a truth table and minimized equations for t_ff like so:

3 Bit Synchronous Down Counter from image.slidesharecdn.com

Found this circuit which uses two jk flip flops but counts down. It is one of the most versatile flip flop circuits. 3 bit asynchronous up counter using jk flip flop | very easy play.google.com/store/apps/details?id=com.arul10012016.

The counter has unused states 2, 5, 8, 11 and a function bit to count either up or down.

Can please someone explain me how do we draw it with all the it should include a control input called up/down. Up/down counter using t flip flops. Prepared with gate & ese course curated by ishali priyam on unacademy to prepare for the toughest competitive exam. It is one of the most versatile flip flop circuits.

The 't' in the t flip flop stands for toggle, so it is also known as toggle flip flop or t flip flop.

The reset pin has to be active high.

To cure this problem, parallel counters can be used.

If cntrl is 0, then the circuit should behave as an up counter.

Can i build a 3 bit modulo 7 counter using 2 flip flops ?, i'm thinking of using the clock as the third bit since it toggles from 1 to 0.

Here, if m=0, this will work as 3 bit up counter and when m=1 , it will work as 3 bit down counter.

All the pins will become inactive upon low at reset pin.
