LOZ-DTUN.* - This program is derived from a calculator
program written by Andrzej B. Przedpelski in the article "Low
Impedence Double-Tuned Circuit" in the May/Jun 1982 issue of
RF Design magazine; pgs. 24-28. The circuit is basically a
double-tuned bandpass filter with impedence matching on both
ends.
The program was originally written for an HP-41C/CV
calculator but is converted to BASIC for use on the IBM-PC.
The user enters the desired circuit Q, the desired
source and load resistances, a value of inductance the
designer would like to use and the measured (or guessed-at) Q
of the inductor. The program then calculates the component
values required and presents the user with a menu to allow
him to twiddle with his entered parameters until he find a
circuit that meets his specifications.
