Comment by periblepsis on Design a 4-bit parallel counter using D-FF
What do you mean saying that zero depends two states in the sequence and then saying they aren't wanted? I'm confused. If you will clarify exactly what's needed it will go a long way in getting a more...

Since you are asked to plot "over time" then can you see anything there that might alter Vx over time? Or do you see nothing except that Vx should stay the same?

I'm rather weirded out by the direct application of a switch to L1 against a backdrop of a 50 Hz bridge rectifier without any attempt to develop a relatively stable DC source at the left end of L1....

Answer by periblepsis for Step response of a tricky RC circuit
The question you were asked is quite good. Some applicants will simply fail the question in some way. Like you did. Others will give a correct answer but not recognize anything beyond the obvious asked...

@CoderBittu There are some reasonably priced options to buy. But you are also a self learned hobbyist. I cannot think of a better project and motivation for learning. So you might consider both...

You get the right values, within the precision given, for the critical frequency and Q. You either found the right formulas in a book or else you derived them, correctly. I don't see how you could not...

To perform a current limit function with only one resistor you need to have substantial excess voltage overhead dedicated to the resistor. But I don't know anything about your circuit. So perhaps start...

Accurate, by definition, means traceable to standards. And so the first question I have is to have you define the required accuracy and the standards organization to which it must be traced. (NIST?...

Take a look at what you have and figure out what you can remove without affecting their functions. For example, motor casings may be a solid surface but you can use tools to remove much of the casing...

TnF, There's too much abuse of the term LDO. So I don't know whether you mean it with precision, or not. But broadly speaking, any voltage regulator will have a range over which its output will be...

It appears that you cannot observe a table with understanding. That alone is the more significant problem you need to work on before complaining about designs.

Personal or commercial product? Also, although more recent vehicles often include circuitry to reduce the impact of load dumps, older vehicles do not. And these can well exceed 100 V.
