I've got to do a class project on Zero-crossing detectors, comparators and Schmitt triggers all using 741 op-amps.
I know all the basics about 741 and also how the above circuits work.
I need to do a project that shows practical applications of the above mentioned topics.
Please help me as I need to submit the synopsis in the next two days!!!

I really hope you'll all come up with something!


Actually colin she's actually asking for help in a another thread, new poster student obviously but they just want information, just ignore this thread as she's already getting help in the other one. I don't understand why these teachers can't actually teach their kids something.
