PROGRAM FOR CALCULATION OF QUARTZ FILTERS
Quartz 220.127.116.11 rus
This program is designed to calculate staircase quartz filters on the same resonators by the method
G3JIR (see "QST" No. 11/1980) and UP2NV (see "RADIO" No. 1-2 / 1982) .
It implements the construction of the transfer amplitude-frequency characteristic of the filter, taking into account the complete equivalent circuit for the replacement of a quartz resonator consisting of Ld, Cd, Rd, and Cs .
Unlike similar programs, this program avoids the errors caused by the presence of a quartz resonator with static capacitance and active resistance. The frequency response is produced with accuracy up to 1 Hz in frequency.
In the program, it is possible to scroll through and analyze any area of the frequency response .
At the end of calculations and simulation of the filter, the results can be printed out on the printer.
Works from under Windows 95, .. 98, ..98x, 2000, XP .
