The four files FILDES, FILPLT, FILSYP & FILTRP are all part of a filter
design program written by Tim Regan of National Semiconductor Corp. They
design LP, HP, BP & Notch filters. They use Buterworth, Cheb. & elliptic
functions. From the filter specifications the order can be found. Finding the
pole & zero
frequencies and Q'S is the next stage. The response may be calculated for
either a linear or logarithmic frequency scale.
For more info on these filter programs, see "Switched- capacitor hand-
book", april 1985 by National Semiconductor.
THE FILE "RESRAT" FINDS THE OPTIMUM 1 OR 5 % RESISTORS FOR A
SPECIFIED RATIO. IT CALCULATES THE % ERROR.
THE FILE "MF10RES" SELECTS RESISTORS FOR THE MF10, DUAL 2ND ORDER UNIVERSAL
FILTER"
THE FILE "SWITCHING" DESIGNS SWITCHING REGULATORS USING ATIONAL'S LH1605,
HS7067 AND HS7107.
