When the outage occurred, I observed the following The L1/G voltage difference was 120V (good). The G/L2 voltage difference was 90V (bad). The L1/L2 voltage difference was 30V (very bad!). If t...
$$\boxed{\text{What maximum value of } I_{OUT} \text{ did you have in mind?}}$$ Using $I_{OUT}$ and $V_{OUT}$ we calculate power uplift. Using power uplift and switching frequency, we calculate how...
These are my general thoughts: - Easiest - power management IC (PMIC) Smallest footprint - PMIC usually Cheapest - usually PMIC (for a certain minimum performance level) Highest performance - PMIC...
Is C2 here to protect the voltage source from thermal noise? There's absolutely no chance that any level of thermal noise produced by a resistor will be sufficient to cause any reasonably desi...
CAN is asynchronous and, if you receive a string of consecutive zeros, the UART mechanism that turns raw CAN data into "a byte" might have to wait a great deal longer than 1 bit of data before it c...
It appears that a user's reputation score has disappeared from the top ribbon at the side of the user's login avatar/picture. Is this an intentional thing?
There are plenty of ways a single diode and a couple of resistors can perform multiplication (RF mixing). Consider this circuit that takes two inputs (a 1 MHz sinusoidal carrier wave and a 10 kHz t...
in my schematic we must add R1 correct? Yes that works except: - One last question if we deliver voltage to a house are there varactors which can handle 120V AC No, they don't exist.
if we don't apply a sinusoidal signal at the input s may become a complex number $$$$ All real-world signals exist only on the $j\omega$ axis. Consider that a complicated signal can be broke...
Any electronic component or module you buy for a project or design should have a data sheet. By data sheet I mean a portable document format (PDF or equivalent) like this: - Do not assume that...
Currently there are $\boxed{\color{red}{\text{three}}}$ downvotes so maybe someone can explain why this has happened. Anyway, on to my downvoted answer: - You have "mentioned" the threat (the ESD ...
without the use of differential equations or simulation Then use Laplace transforms to derive the transfer function. Multiply it by 1/s to get the Laplace result when a step is applied then, u...
what is the maximum DC voltage I can bias this connector at I don't see why this shouldn't be treated like any other component that has a maximum voltage stated in its data sheet or documentat...
The question below was raised by a "new user". The identity of the "new user" was deleted because it was found to be an alias of an already suspended user: - So, why is the question still active...
Which will be the total inductance of this circuit? Quite simply, if both the individual 1 henry inductors are perfectly magnetically coupled then, the net inductance will be 4 henries. If bot...
I need to know what is the difference between differential amplifier and differentiator A differential amplifier amplifies the difference voltage between two signal voltages. A differentiator ...
A work around has been found for this and I'm sure this will get a proper fix before long: - Go to the edit button for your answer (for example) and press it Notice that there is no live preview s...
$\color{purple}{\text{Are we there yet?}}$ No, it's not ready: - The embed image doesn't seem to work anymore on the EE part of the site and neither does it work here. It did yesterday because I a...
Very short answer - get rid of downvotes on answers; just don't allow them In fact, wouldn't it be a better policy to award upvotes to people who point out errors. That would encourage folk to wan...
