% FIR Window Bandpass filter designed using the FIR1 function.

% All frequency values are in Hz.
Fs = 10000;  % Sampling Frequency

Fstop1 = 299;             % First Stopband Frequency
Fpass1 = 300;             % First Passband Frequency
Fpass2 = 3000;            % Second Passband Frequency
Fstop2 = 3001;            % Second Stopband Frequency
Dstop1 = 0.01;            % First Stopband Attenuation
Dpass  = 0.057501127785;  % Passband Ripple
Dstop2 = 0.01;            % Second Stopband Attenuation
