This is going to be a set of classes for analyzing and designing Digital Filters. The functions will include time domain response, frequency domain response, bi-linear transform (for converting between frequency domain (continuous) s domain functions and Z (discrete time) domain functions. This project has just started as of 11-24-2015. The purpose of this exercise is so that I can better implement analog modeling digital synthesizers in both micro controllers, both AVR and ARM processors, as well as FPGAs, such as the new ARTY board by Digilent.
