Comment by periblepsis on what is "carry in" in full adder?
Try just adding two binary numbers by hand on a piece of paper. Line up each binary digit, appropriately. Then consider drawing a thin vertical line between each binary digit and thinking about that...

The sensor's model is a capacitor and a resistor. These are orthogonal, so writing impedance between 1 and 30 meg isn't entirely clear about the capacitance range and the resistance range. Can you add...

I'd want to start by examining the mechanical design and working out some details about how aging may impact friction and other factors. Then I'd want to be able to calculate the expected amount of...

Ladle, is that essentially 46 sheets to penetrate? Or about 9 inches of material? Perhaps it would help if you provided a drawing. Have you worked out the specific heat and the heat of evaporation for...

You will need one of these. ;) Not exactly cheap. But capable.

@ArturKrush In directed graph theory, which is important here, you don't get to create two differently named vertices that are the same vertex. B and F are the same vertex. So you have to pick one name...

@PhillDonn I'm just being direct in writing. I was discussing your error in analysis as shown in your question. The only thing that matters to me is that what I write helps you.

@Isacco Have you considered just buying their evaluation board? It's not overly expensive. Test with that. It may help you quickly find problems. Are you using a solderless breadboard?

Vrisk, You will need a much more crafted design than that one! You will also likely requires "speed ups" to be included in order to forward ahead the rising and falling edges to the output stages. If...

Answer by periblepsis for Node Analysis with CCVS
It looks as though you are trying to use KCL and that the middle node at the top of your circuit is being called \$V_1\$ in your first equation in your question. (Potentially confusing, as you also...

Some CPUs include more than one voltage rail: e.g., an I/O voltage and a CPU core voltage rail. Some of the CPU core voltage rails have a range over which they can operate and the choice impacts the...

user4.., Show your work. You have a wrong result for the transfer function. (Even a simple sanity test shows that much.) So don't skip showing us how you got it. We can't help you spot your error,...

@Schilive Study the Drude model. It's fairly intuitive, I think. (It had to be given it was introduced in 1900, which was four years before Thompson's "plum pudding" atomic model!)

You appear (to me) to have unapplied a-priori knowledge to form more optimal filtering. Given this may be key to some corporate IP, that's all I'll add.

artemis, Note that the 20 Ohm resistor is completely irrelevant. So if you have included it, then you are already wrong. Would you be willing to expand a little on your thinking process? Mine is...
