    Help with Ansys Electronics error please: "The quality of some mesh elements is not acceptable for solution"

    Meshing is always a really tricky issue. It would be difficult even if you called an application engineer for help on it. What you typically want to look for: Anything with like sharp acute angles or self-intersection; also really long narrow lines can be tricky to mesh mostly because it tries...

    Other Summer Research Position Decision

    I did almost only research positions before working in industry a lot of it in nanotechnology and material sciences. I became an RF engineer in aerospace & defense and later a Signal and Power Integrity Engineer for a consumer electronics companies. The experience mattered the most and the...

    Counting of Integrated Circuits by photo or video

    I wouldn't suggest this as an accurate way unless you really put a lot into your own code, but I wanted to share maybe a crude fast way if you know roughly which shapes you are looking for you can use mathematical morphology on a tool like matlab or (free) imagej. On MATLAB i'll use something...

    Other Recommended work for an undergrad (internships, research, etc.)

    Why put all of your eggs into one basket? I would just consider both if they appear interesting to you. If both come back to you with a "yes" then you can think about which one you like more later :)

    Replacing 0603 Capacitors: Techniques and Challenges

    Oh, my suggestion wont work if you're trying to decrease the capacitance :( I think the earlier suggestions sound better you might want to consider those instead. I recommend you share the application or maybe some of the schematic, or both. It might help with suggestions.

    Replacing 0603 Capacitors: Techniques and Challenges

    What's the application? Is it just a test board that you can muck around with. Can you achieve your goals with added capacitance? I'm really bad, but I've done on it test boards... it's a lot easier to just stack some caps on there to add capacitance if that's an option you can consider. I'm...

    Engineering Produce a resonance curve for this circuit between 6 kHz and 10 kHz

    I would imagine plotting magnitude of impedance Z would be a valuable learning experience :) what does L and C do at the resonant frequency, and impedance should you see when that happens? If you had time and wanted to explore, then I would put another pair of these in parallel to it with a...

    Good books to learn electronic devices and circuits AND digital electronics

    What's your background? Will this be your first time doing circuit analysis? Sedra/Smith is very popular I've seen it on almost everybody's shelf (at least within my circle), but it doesn't seem too great for introductory circuit analysis. The book I started with was Introduction to Electric...

    Reflection factor for a microstrip transmission line

    You're in the home-stretch. Almost there! Your notation for this stuff is very strange by the way, but I can see in the equation you discriminate between ZL and Zload. Most people don't do the notation that way. They'll probably prefer the way that I have it above. They usually use Z0 in...

    Reflection factor for a microstrip transmission line

    This part is super important for your question. Lets take a step back and look at a transmission line I'll call ZL2, which has a characteristic impedance Z2, an arbitrary length L, and its load is ZL. What are some things I can do to make its impedance stay the same for different values of L...

    Engineering Frequency Response of High-Pass Filter at 1kHz

    I just wanted to share this because I think some posters and future readers might find this of interest even though I think the question has already been answered very well. I personally think for a graphing problem, that this circuit is intuitive even for an introductory circuit course...

    Other Yahoo! News: Community College units not transferring in California

    I recommend to any (California) community college readers to visit ASSIST.org. I'm not sure if it will work for you, but it worked for me. It's been a long while since I've done that, and so I don't know if there has been any (big) changes or added caveats, but it looks about the same to me...

    SULI Rejection: Can I Resubmit With Unredacted Transcript?

    I missed out on one because some careful eyes caught my birthday on one of my transcripts, and it wasn’t me :( I didn’t know they put my birthday on there and I never noticed it before lol. It couldn’t hurt to ask, but I would consider the opportunity as a no go and look for other paths or...

    Engineering I’m having second thoughts about my job position. How can I proceed with it?

    Something else that worked for me is I called the application engineers and asked if I could get a trial license. They one upped me and offered to do a trial + training a small group of people on the team. They sold it for me and I got to learn a few things.
