Homework Statement
Hello everybody,i am new member and i hope that you can help me out in understanding the attached circuit.our lecturer gave us this circuit and asked us to do literature research and try to understand how the circuit work (the parallel port,the transistor circuits,the analog-to-digital converter and the capacitor)
Homework Equations
The Attempt at a Solution
i - i have done a lot of researches to understand parallel port and i think i understand nearly 90% of it.
ii - i noticed that the transistor circuits are repeated but with few minor changes (VR1?VR2?VR3?VR4?VR5 and R7?R12?R17?R22?R27).
I would really appreciate it if you guys can enlighten me
