it took us the whole Academic Year 2005-2006 to make this study.. and with the help of a lot of people especially audioguru, we were able to have the final manuscript printed and hard-bounded.. it took me some three months to have the courage to upload it here at eLab..  Anyway, i just want to share it here because, again, without eLab, i would have never come up with something like this.. 

thanks again..  ;D i am so grateful..

BTW, my work is open to criticisms.. you'll do me a great favor if you correct the mistakes i made in explaining some things in there..  8)

Hi Logan,
You have a very nice manuscript.
It is too bad that you didn't have enough time to fix the faulty circuit by using a CD4069 hex inverter IC.

Correction: A Schmitt trigger uses positive feedback, not negative feedback to allow it to switch very quickly even though it has a slowly changing input.
