Comment by periblepsis on Karnaugh Map with don't care condition
So, your map is this? Product of sums would be (X0+X1)(X0+X2'). Not so?

@VoltageSpike Plagerism has a legal definition that requires the wrongful appropriation of another's expression of ideas, claiming someone else's work as your own. It's hard to make that case here as...

Okay, German precise thinking is nice. But +1 for the black square at the end! ;)

Glad to hear it! I can't begin to list how many times I've overlooked something obvious in hindsight. ;) You are allowed to select your own answer. You should to that, I think.

Answer by periblepsis for Kirchoffs voltage law with 3 voltage sources
I'll use your original diagram, but add names to the voltage sources and pick a specific direction for the current requested in part (a):They didn't specify the direction, so that means you get to pick...

Insipid, @Mattman944 Is telling you exactly how to visualize it. It's actually all you need. Independent events can still smear through multiple bits. (Or just one.)

Plugging into my calculator, using Freq or omega (add 'j'): 100, and typing in 63.54/(10mH+(4.7mF|(0.5mH+2.3))) it gives 0.0896123054 - j10.6870633 or 10.687439 ∠-89.5195793 as its output.

@Dark Last I heard, manufacturers were moving from COTS ICs + SHA-x encryption over to ASICs where they control the entire process, including physical signalling methods. You don't show much to go on,...

@GwenGrand Both Q8 and Q9 are set up for maximum voltage gain and maximum signal distortion (signal-dependent voltage gain which distorts the resulting signal.) There's no global NFB to linearize this...

The question should be less about average power over the die and more about the concentration of dissipation at some smaller point within the die where more valid concerns are manifest. You cannot well...

In this particular example of drift, is there only one task? task_num == 1 is true? Or what is, exactly, going on in your test? Are you enclosing the disclosed code inside of yet another while forever...

Since for one bipolar the collector current changes by a factor of 10 for only 60 mV difference of its Vbe, putting two together like that means everything is quickly shifted to one side or the other...

For 20 dB of voltage gain there's no need for very large resistance values. Using very large values is done sometimes in transimpedance amplifiers, but then may require guard rings and PCB cutouts to...
