This 'EMCFiltr' software is a dedicated EMC Suppression Filter Simulator.
It is unique in two ways:-
Requires no schematic drawing or Net-List entry.
It uniquely makes allowance for Frequency dependant variables implicit in practical Capacitors and Inductors, providing simplest possible, realistic Real Life simulations.
The required Frequency dependant variables are calculated automatically from data stored in the program.
This 'Evaluation' version is fully functioning, except that final analysis is restricted to the 'Two_Tee' filter style.
This version now has an expanded range of component model data and wider choice of real life components for use in simulations.
This version has been enhanced such that the alternate format screens needed to overcome font and size etc. restrictions for VGA screens are incorporated in the one version. Consequently this version adapts to work regardless of any change of the Windows screen resolution used.
Pre-installation.
Copy the files which you un-zipped from the downloaded file, EMCFILT2.ZIP, into an empty directory, then using PKUNZIP, unzip the main file, FILTER.ZIP.
To install the 'EMCFiltr' software use the Windows SETUP program to run "setup.exe" from this directory.
If you have not previously used a Visual Basic Windows program, you possibly won't have the run time file "VBRUN300.DLL" already on your hard disk in the Windows\System directory. In this case the setup installation will fail giving the message "Could not find VBRUN300.DLL", a required file for all Visual Basic compiled programs.
To minimise storage and download times, many archive sites insist this fairly large file, VBRUN300.DLL, be excluded from downloaded software program packages.
This file, if not already on your system, is commonly available and can separately be downloaded from almost all software archive sites. If not already in your Windows\System directory it must first be obtained, unzipped as necessary, and copied to your Windows\System directory, before installing the EMCFiltr software, otherwise the software installation will not complete.
The current version of VBRUN300.DLL used to write this software was 3.00.0538 12/5/93 unpacked size 398,416 bytes. This version or newer, is required.
