This isn't something I know about. But if I wanted to know, I'd certainly call around and ask. I've found good conversations with a physicist or polymer chemist assigned to the sales team, for example....

Seems as though you know where the problem is, already. If this were my problem (it's been too many years since, so maybe I find the time and maybe I don't) I would look over the assembly options for...

I have a John Deere tractor here that I use regularly. And I have a 6' wide tiller implement, too. I've never considered automating the process of lifting while turning. Partly, because I don't think I...

It's listed here for some reason. It's been too many years and there have been too many slightly modified cores since Intel's 8031/8032 for me to feel confident, anymore. (SiLabs twisted me up a bit...

Answer by periblepsis for Understanding a complex rectifier circuit
I'm not going to address tweaking your resistor loads to get voltages you want. I'm leaving the \$325\:\Omega\$ resistors out of the schematic, for analysis purposes.It's better if you see the...

What worries me is the level of work you are requesting in an answer. If I were to lay out a system with one, two, or three internal buses, the addressing unit, execution unit, ALU, and a variety of...
View ArticleComment by periblepsis on Schmitt trigger confusion
Seems like you want a general approach using math. I discuss some of it here. But M. J. S. Smith, "On the circuit analysis of the Schmitt trigger," in IEEE Journal of Solid-State Circuits, vol. 23, no....

case (a)The lower opamp is just a follower. So its output will be the same as its (+) input. This means you can reduce the diagram to this:And you know that \$i_o\$ must travel completely through...

I didn't want to write any of your polling or display code. I just wanted to find out if I could set up the two timers and have them run in the MPLAB X simulator and hopefully produce results I...

@kwiky Now that you know that the triangle isn't an amplifier, but ground reference, can you show any attempt at the math?

try_except, I only just dropped into this question. In less than a second skimming the schematic I noticed something missing -- a capacitor parallel to \$R_4\$. The next thing I noticed is that you are...

I know that I've seen published formulas. I can't recall where. But the books were very old(circa 1940's). It was in a very thick book and there was a lot of prior knowledge leading up to them. I...
View ArticleComment by periblepsis on Thevenin equivalent resistance of a network
The two paralleled resistors do result in \$1.5\:\Omega\$. But the current source across them develops an equivalent of \$-6\:\text{V}\$ (referenced to ground). So \$3\:\Omega\$ + \$1.5\:\Omega\$ does...

@tobalt Good point. Probably not needed. I just tossed it in, thinking about wayward screwdrivers shorting to random things. It's likely not needed. So I take your point and I'm glad you added it here....

Luke, It is wonderful that you are using this as motivation to learn, adapt, and create! But one of the very first things I do when working in unknown territory is to carefully document what I can see...

SerArwyn, The whole idea of AGC is discussed here in Wikipedia: "The signal to be gain controlled (the detector output in a radio) goes to a diode & capacitor, which produce a peak-following DC...

@MichaelB.Ortiz I would probably approach this problem using two Schmitt triggers: each of them set for a small noise margin around the two thresholds. Combining the outputs to produce three output...

Velibor Simovic, you forgot to include Figure 2.36. Since Figure 2.37 connects to it, others will have a harder time following the author's logic and therefore a harder time helping you see what the...
