About gmeteor

gmeteor is a tool for designing discrete-time equiripple filters with linear phase and a finite impulse response (FIR). `gmeteor' runs on systems that support the Guile extension language from the GNU project (for example, GNU systems running on a Linux kernel). `gmeteor' is free software distributed under the terms of the GNU General Public License (GPL).

Examples

With gmeteor, you can design filters with an arbitrary frequency response. In contrast, most filter-design program only allow you to specify piecewise-constant frequency responses. Below, you can find examples of how to specify frequency responses in gmeteor, as well as the filter that gmeteor computes.

• A simple low-pass filter
• A low-pass filter with weights
• A filter with point constraints
• A differentiator
• A filter with concavity constraints
• A generic constraint-based filter design
• Zero-order hold compensator
