I always start by first redrawing a schematic I'm given. Just that process alone helps me, as I recognize sections. Sometimes, I just isolate out the parts I recognize and then see what is left over....

Wouldn't that be a way to filter noise/isolate between two rails, VCC and a motor PVCC, using an inductor and capacitors?

I love SMAW, MIG, and TIG welding as a farm hand. I enjoy the work very much. It is part of who I am as a person. But I don't understand your situation well enough to be of help. Can you add more...
View ArticleComment by periblepsis on Single pulse when input voltage crosses 10v
@WilliamFitzPatrick You are asking for a schmitt trigger with a set trigger voltage followed by a one-shot with a set pulse width. It may be possible to consider one of several 74xx series devices for...

If this is for a commercial board where the vector throughput is a core function to the application, then wouldn't this have been promoted to a research issue to be resolved very early in the project?...

You can use a discontinuous boost circuit with adc feedback in the loop. A single programmed word will drop the voltage slightly. But with the right cap size, it will stay in range. Then add a few more...

Answer by periblepsis for Total Resistance
Here's my approach to simplifying the schematic:From step A to step B it's just assigning a ground reference and erasing one unnecessary wire. Then to step C I just moved the left part over to the...

electrical, if you are willing to invest some time, I'd recommend looking into high efficiency LEDs to use together with something like the LM3909 (don't know if they are made anymore.) It can be done...

You are beating this thing to death. You already have opinions from the prior question. Your formulation for Vout is correct. And the value of I1 is not zero. That's obvious as R1 is connected to a...

@MikeWazowski It's this easy. You really need to dump the professor.

Retro, transmission gates are found in Neemann's Digital program. It replaces Logisim quite well. You may want to look into it.

If you break apart these two sections then you have two independent 1st order filters. And if you mathematically combine them without taking into account loading, then swapping them around doesn't...

I can't even begin to get a hold on what you want. The word standard is there, but in the usual cases a 3rd order is broken into a standard form 1st order and a standard form 2nd order (and there's at...
View ArticleComment by periblepsis on Why do we need a diode in an AM demodulation circuit?
If you are going to google, then look for "square law" detection and detectors. This makes the output proportional to the signal power. 100% modulation on a double sideband full carrier will have a...

You don't say much about the class. And there are so many different kinds of multistage amplifier sections to consider. But taking into account what you were told, I suspect your question comes from...

Please select your answer so that it can be considered closed and doesn't keep attracting eyes wondering if there is something more needed. And good job with your own debugging of the problem!

Too little information. This could be a colored/clear broken/crushed glass sorter for all I can tell. And what signals look like, in time, isn't ancillary. It's central to narrowing down suggestions to...

If discrete is a requirement, I might first consider current-steering such as used in ECL. Easy to understand and assemble and it uses resistor degeneration to deal with part variations. A differential...
