what are they? Being a nice guy, I download and extract the writeout:
EETools Version 1.0
Calculator for the electronics engineer
EETools is a program designed to help simplify an
engineers job in electronics R & D. Contained within the
software are 48 common formulas used in electronics set up in
a convenient format. Besides having a menu driven system for
quick routine access, most of the formulas require no
transpositioning. You simply fill in all of the known
variables leaving one blank, and the program solves for the
unknown. There is also a graphing feature which allows you to
plot and hardcopy functions.
To use EETools, simply type "eet" and hit <enter>. The
rest is very straightforward. A help bar at the bottom of the
screen displays the available commands. Getting through the
menus to a function of interest should be no problem. After
reaching the correct routine, you will notice a formula in
the upper left hand corner of the data entry window. If the
words "APPROXIMATION INHIBITED or A.I." do not appear after
the formula, then you may fill in all but one entry and the
computer will solve for the blank variable. If your data was
properly entered, the result will be displayed in a new
window.
EETools contains a global array of electronics variables
which makes it convenient to move from one function to
another and transfer the results. You could easily calculate
the inductance of L34, then find the inductive reactance and
finally solve for the impedance in the circuit without having
to retype the results in subsequent formulas. However, if you
wish to start some new calculations, simply type <Ctrl-K>
from the Main or Sub menus to clear out all of the global
variables. Data entered into the functions can be in decimal
or scientific notation (.000001 or 1e-6). The result will
usually be in scientific notation, however if you return
immediately to the same function you'll find the result in
decimal.
EETools checks for several different errors to make sure
the evaluator can handle your data.
Before evaluation:
1. Not enough fields were entered.
2. Too many fields were entered.
3. A value outside the dynamic range of the variable
was entered. All of the electronics variables have a
dynamic range to their values. For instance, you are
not likely to find a 10000 Farad capacitor or a noise
