Actually, I dont want to ask my colledge for help. Everytime ,for each guy I ask for help, I need expain the entire system and principle of a frequency counter to him. They just keep asking questions instead of answering mine.
In defense of the hardware guys, there are a lot of questions that NEED to be asked (and answered) before a design that fulfills your requirements can even be attempted. I don't mean to be unkind, but you skipped all of those questions, designed the software, and now you want someone to hand you a hardware design that solves the problems you are having. From what I can tell, you still don't even have a good concept of what the hardware needs to do, much less how to specify these needs as coherent project requirements -- and even less how to actually design the circuitry you need. Furthermore, when someone suggests something that might fix a glaring error in your design, you say you can't do that because (for example) PNP transistors are too expensive.
Ask any competent engineering manager and you will learn that good analog design engineers are the rarest and hardest to find development team members, and that getting the hardware right is very often the hardest part of any design (note that I did not say, "most time-consuming" -- rather, "hardest").
So, now you need the analog hardware for your counter, and you have the mistaken impression that it shouldn't be any effort at all. Hopefully, you are now beginning to understand that at least as much good thinking needs to go into the hardware as into the software. And hopefully, you have reviewed the analog circuitry of some good commercial designs to see what sorts of things good analog designers have done in the past to solve the same problems you are facing.
You said yourself that you don't really know anything about analog design, and your existing circuit and your comments here on the list show that to be an honest and true assessment. But you also have resisted advice you have gotten from experienced analog designers, and now you say you can't even be bothered to answer the questions of people who would try to help you!
At this point, I'm afraid that whatever is posted on this thread isn't really going to help you improve on what you have -- it is just so much wasted internet bandwidth. You need to learn at least enough about analog design to ask and answer intelligent questions about your needs, and you need to be willing to consider the advice you receive, before any of this can help you.
