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. Geir A. M. Drange BIH, Bergen, Norway INTERNET: el02@hp825.bih.no
