## Description

"FIR Filter Designer" is an Android app that enables users to design minimal-order finite impulse response (FIR) digital filters based on their specific performance criteria. It generates double-precision filter coefficients or implements the filter in C/C++, C#, Java, or MATLAB/GNU Octave. The app ensures approximately unity (0 dB) gain in the passband and allows users to easily share the results via email. Complete source code is available online, thanks to contributions from the open-source community.
