% FIR least-squares Bandpass filter designed using the FIRLS function.

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

N      = 50;    % Order
Fstop1 = 2980;  % First Stopband Frequency
Fpass1 = 3000;  % First Passband Frequency
Fpass2 = 6000;  % Second Passband Frequency
Fstop2 = 6020;  % Second Stopband Frequency
Wstop1 = 1;     % First Stopband Weight
Wpass  = 1;     % Passband Weight
Wstop2 = 1;     % Second Stopband Weight

% Calculate the coefficients using the FIRLS function.
