Some linear regulators are marketed as “adjustable”, but all linear regulators create a specific voltage in relation to their ground pins. Since the ground pin voltage can be offset from the …

I want to calculate the cutoff frequency for a specific filter, but I can’t find any formula for that. I know the formula for the cutoff frequency of a low pass filter: $$f_c=\frac{1}{2\pi RC}$$ …

Why is it so that for a signal to be an energy signal it must have power zero and for a power signal the energy value should be infinity ?

I built a mod-16 counter, and the output result is a INTEGER (all the examples I saw used INTEGER). I built a hex-to-7-segment-display decoder, and its input is a STD_LOGIC_VECTOR (wrote it that way …

I know mAh tells how much milliamperes a battery can deliver in an hour. But does that also tell how many hours the battery would last? Sorry but I don’t really get it. If we’re talking about a water …
