; File Notes:
; 1. This file contains FIR filter coefficients and filter structure
;    generated by the dsPIC Filter Design tool.
; 2. The filter characteristics are as follows:
;    Filter Type:Band Pass , Elliptic, 9 Second Order Sections
;    Passband Ripple:                   0.001 dB
;    Stopband Ripple:                   100 dB
;    Passband Cutoff Frequencies:       200 Hz and 3850 Hz
;    Stopband Cutoff Frequencies:       100 Hz and 3990 Hz
;    Sampling Frequency :               8000 Hz
; 3. The filter coefficients are stored in X-Data Memory and accessed
;    via the X-AGU
; 4. These coefficients have been designed for use in the Transpose filter only
