It would help to provide links in your question to the datasheets. Without the datasheets I can only give general advice. Look a the memory datasheet and see what the setup and hold time requirem...
Your question is ambiguous. First, you need to define "rise time". That applies to a step, not a periodic signal. Let's say you have a 0 to 5 V digital signal. The rise time is how long it take...
The component with the coil of wire is an inductor. Judging from the small size, it is probably only a few µH. There are lots of uses for inductors, like for filters, switching power supplies, tu...
It's hard to answer your specific case since you didn't label the layers in your picture, or which traces are doing what. That said, a few traces crossing each other on different layers is not muc...
An induction motor with its shaft held still will mostly look like an inductor with a series resistance electrically. However, there will be some issues: It will be difficult to guess the inducta...
how much higher can i go in current ripple RMS None, of course, at least if you want to rely on anything else the datasheet says. The heating is a function of the RMS current. No, you don't get ...
The thermal noise of a resistance depends only on that resistance. However, there is always some parasitic capacitance. That capacitance against the resistance causes a low pass filter. So in a ...
When measuring signals at different points on the skin of the body, you don't usually want to connect the victim patient to ground. Usually you use an extra electrode connected some distance away ...
I agree with this approach. Categories should only be created when they are expected to have reasonable traffic. A category with only chirping crickets is an anti-advertisement. Take a look at t...
I'll let someone else answer about the device physics. I'll answer from an electrical engineering standpoint. The answer is: Maybe, but it doesn't matter since you should be considering worst cas...
The difference between your two options is which polarity the input floats to when left open, and whether there is an overall inversion. Adding the inversion in the firmware would require one more...
First, the time dilation experienced by a satellite is tiny on a human scale. It takes sophisticated algorithms and lots of processing power to measure time differences between a spot on earth and...
The poteniometers (what you label as "variable resistors") are almost certainly just floating pots. If their ends were permanently connected to power and ground, then they'd be voltage sources, not...
If you don't care about efficiency of the overall system, then a zener to limit the voltage will work. You are right in that a series resistor is not needed since the source is power-limited. One...
Your generator constant is 2 V per Webber-Hz, or 2 V/(Wb Hz) = 2 (V s)/Wb. You somehow got a value of 5. The rest of your calculations are probably off due to that. Added I didn't have much tim...
To properly answer this question, you need to show us a real circuit with a capacitor across the supply. There are various reasons a capacitor across a power supply might make sense. Protecting t...
You are making this way too complicated. Go back to the basic problem definition, which is you want to get a digital reading of the current sunk by a current sink, with the valid range being 4-20 ...
It's not clear that the problem is. It seems you want to interface to this "digital air pressure regulator" via two 4-20 mA current loops. For reading the output, it should be as simple as a 24 V...
I think the biggest reason is that it may be difficult to control your function generator with an output of only 5 mV. Some function generators have different output ranges that are switched, then...
I was the one who started that list Elsewhere. I thought the same as you, that a few common abbreviations would be good to have in a single place. However, it quickly turned into a mess. After o...
It seems you have ground loops, and possibly having multiple ground connections shorting out your signals. Your hand-sketched diagram is a good start, but you need to show all the ground connectio...
You are asking how to analyze this circuit: Forget about what you think it should be called. Before attempting to model specific aspects, first try to understand the circuit. The opamp provide...
A resistor is not a good model for a saturated BJT. According to your graphs it is, but those are simplified. There isn't really a single slope for all base currents as your graph shows. Even if...
I have decided to try design a band-pass filter with a cut-off frequency of 10kHz and bandwidth of 2 Hz. It's "10 kHz", not "10kHz". There needs to be a space between the number and the unit. ...
Personally I wouldn't want another category (what you seem to mean by "section"). I also don't think this should be a code review site. However, asking for validation and advice on small and spec...
