Subject: Calculate Standard Resistor Values

                         Standard Resistor Values
                         ------------------------

Following are a few programs that will calculate standard resistor values.
E12, E24 and E96 are supported. (Others can easily be added.)

Usage:
------
Place value on stack. Run 'STD12', 'STD24' or 'STD96'.

How it works:
-------------
This is left as an exercise to the reader...



Unity-Gain Sallen-Key Low Pass Filter.
--------------------------------------
This program will calculate standard value components (using the above
programs) for a second order Sallen-Key low-pass filter. The program
will ask for frequency and Q-factor, and then scan through all the
standard values to find the best matching ones. Progress is displayed.
The program can be interrupted by pressing a key. It will then return
the best values found to stack as tagged values.
