OK. I am thinking of apply pulse input which called 1-pps (1 pulse per second).To achieve this,firstly I include pulse input which is 3.4V and 60Hz (60 pps). After that I use 7490 (mod10) and 7492 (mod6) the output will be 1pps. I tried it on proteus proffesional 8 but it does not work. 1590606443199.png
