The counter can count from 0 to 99 and count down from 99 to 0 . Once the reset button is pressed, the counter will reset to 00. If the counter counts from 0 to 9, one of the seven-segment displays should not display any character.
Hint: The control circuit contains 2 decade counters and 2 decoders.
If you all have any circuit diagram , please post it , or also can teach me how should i do. Thank you very much.
