hi,
Which type of counter are you using, post the model number.?

How many counters and at what frequency are you clocking.?

EDIT:
If its the counter circuit I helped you with this week, then the LS192 are synchronous counter are glitch free.

yes it is the same countr, but I did not use the LS I used, the HC.
when i simualated the results I found a glitch. you can see it in the attachment,
i know you have to use a strobe, but i am not familiar with it and do not know how i can connect it on proteus.

and i used freq 1Hz only

hi,
Thats not a glitch, thats the /PL pulse that reloads the counters with the bit switches.!
