I think simple LC resonance is easy enough to teach, especially if I do a low-pass on the board. You get the multiply by 1, complex conjugate "trick". Then it's just a matter of 1/10 vs 1/100 vs 1/1000 vs 0. You don't really need calculus to see what's happening there intuitively.

I've spoken with a few colleagues that have more experience with these types of contracts than I do. I received clarification from the client as well that this is largely an academic project. My colleagues also agree that this seems odd. I haven't signed any before. I might take up the...

I'm pretty well versed in electronics, including filtering. I would not claim to be an expert, but analyzing the circuits with the students will be no problem. I'm also pretty well versed (again, no expert) with designing/building/troubleshooting circuits. I have only officially taught DC...

It's not the NDA part. It's the no co-author part that seems odd to me. All I know/can share at this time is that it's theoretical work and I'll be doing a lot/all of the math for a concept. This may or may not result in publications, and the publications may or may not actually be something I...

I see that there might be a difference, but the differences listed in the powerpoint shouldn't affect how the circuit works. Yes, I have access to everything in the physics department, including function generators, o-scopes, etc.

Hi, I just received an NDA for some work that I may be doing with a client. I will be coming up with a mathematical formalism for their idea. I have a question for anyone who has done similar work. There is a section on co-authorship which says that I won't be included as co-author on any...

Thanks all for the responses. To address @berkeman , camp is loose. It's on a college campus in the physics department. @DaveE I'll check this series out. Thanks. @jedishrfu I just made up those numbers based on what I feel like it will take for me to gloss over a lot of the stuff. Maybe explain...

Hi, I'm working a day for a physics camp in about a month. I have about 6 hrs (less for lunch) with about 10 or so high-achieving high school students. I need to come up with a project that can be done in that time. I can do prep work ahead of time (like making pcb boards, etc) to make things go...

OK, I'm messing with the program now. I'll keep that in mind for when I get further into the circuit.

I did mean circuit simulator. Thank you.

OK, thanks, I will keep that in mind. This might turn into something where I will have to be very concerned with accuracy. Only time will tell. I appreciate the help everyone. One more question, is there a good online simulator that's free (actually) that I can use? All of the ones I've used so...

Actually, something like this clipper and multiplier might work. Multiply Vout by my source signal. I might need a latch as well. I never consider diodes when I'm trying to design stuff, I'm not sure why.

I would prefer to do it analog. It's just coding with psoc or arduino, which is easy enough. It's partially an exercise/trying to understand circuits better, partially I want to build something.

Hi, I am ultimately looking to be able to have an analog circuit with an amplifier that uses a pot for the resistor over the op amp (maybe there's a better way, let me know if there is). I want to be able to control the shape of the gain roll-on/roll-off, and have it be functions of R...

I see I misunderstood "giveaway" as a contest of some sorts. Thanks for the clarification.
