2-07-02: Began with time domain approach and designed 3 filters in Matlab.
2-14-02: Filtered single freqency tones through each of the three filters
3-07-02: Determined the center freqency of all eight filters and designed each in Matlab.
error in high frequecy filter's center frequecy and corrected the problem
pre-warping. Obtained the difference equation for each filter.
the difference equations to Direct Form II to minmie memory storage.
C++ design of a single filter.
