Hello to all, i am a journeyman electrician who is trying to get an electronics degree. my assignment is to build a logic tester from a kit and write a report on it. one of the requirements of the report is to justify the existance of every component in the project (as if to a potential client) to show no extra parts are included. i assembled the kit and it works according to the test procedures. while i understand most of what goes on in the design,i have a few questions:
the first thing after the probe is a .001 microfarad capacitor in parallel with a 100 kilo ohm resistor, how do i explain this?
also the probe sees a couple of diodes, one with its cathode facing Vcc and the other with its anode facing ground, i'm thinking these bleed off excess voltage to protect the rest of the circuit?
the kit is an elenco lp-525k
also it is not considered cheating if i make reference to your help in the bibliography
thanks for your help
