Increment and decrement counter

Hello,

How to increment counter upto 5 and after reaching to 5 start decrement it till 0 and again start increment from 0 to 5 and from 5 to 0 continuously, by using simulink blocks.

Thank you

Use a 'Unit Delay' block. That is the counter. Add a number to it. The number is either 1 or -1.

Use S-R Flip-Flop block to generate the number. Its output is either 1 or 0 but you can multiple it by 2 and then minus 1 to get either 1 or -1.

Compare the counter value with 5 and 0 to get the Set and Reset signal for the S-R Flip-Flop block.

Hello,

Yes I can implement by using up and down counter but I am not able to find switching from up to down counter.

Is there any solution using just simulink blocks not by electronics toolbox?

All blocks come from Simulink.

why do we use SR flip flop
