Formatting data dictionaries in LaTeX
I would like to write out some data dictionaries for a program design document in LaTeX, and I am looking for an efficient way to do this. I want to write snippets that look like: Name = FirstName + (Initial) + LastName FirstName = 1{Character}32 Initial = Character LastName = 1{Character} Character = [ A-Z | a-z | 0-9 | ' | - ] It's important that these are lined up at the = signs - they look ugly without it.
Why does I²C only have pull-up resistors (interview question)?
To expand on Jon's answer a little: Yes, it is all to do with which MOSFETs you want to use.

How can I read the graph of a low pass filter
What does transfer or Vout/Vin mean, and why is it on the y-axis? Because I don't understand this, I can't understand the graph either... You could make the input signal \$V_{in}\$ anything that you want and solve for \$V_{out}\$. That's fine - it's just a bit of math. However, if you wanted to change \$V_{in}\$ to something else, then you'd have to re-calculate everything. You haven't learned anything; you've just solved the circuit for one signal.
Ribbon Cable Wattage
The maximum voltage is defined by the insulation on the wire, not the gauge of the wire. It is the voltage (worst case) that the insulation can break down. The maximum voltage, as well as the maximum temperature, should be printed on the cable. The maximum current is defined by the cross-sectional area of the cable (AWG number).
