- 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.
