RM software generates output in a variety of designer-friendly formats including:

HTML report with schematics, filter coefficients and implementation notes
Cleartext and Excel report files suitable for drawing characteristics using your favourite graphing tool
Simulation-ready SPICE files

Book

RM Software documentation is available directly while using the software in PDF, HTML and powerpoint. Software also includes video lectures that guide designers through the process.

However, to fully understand theoretical basis for implemented algorithms we recommend ordering accompanying book Electronic Filters - Theory, Numerical Recipes, and Design Practice based on the RM Software. Read the book online, buy chapters or order hardcover directly from the publisher.

History

RM software is a collection of console applications (“programs”) for analog and digital filter design. The first programes were initially developed by prof Vanco Litovski in early 1970s in fortran and later ported to C programming language. Then in 2010s, additional programs were added and enriched with novel and modern filter design approaches.
With over 70 programs, this was somewhat hard to navigate so a web-based user interface was added to guide design process and launch appropriate programs.
Finally, in this incarnation, a server-side app and a terminal emulator are provided to access and run RM Software remotely.
