% FIR Window Bandpass filter designed using the FIR1 function.

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

N    = 50;       % Order
Fc1  = 600;      % First Cutoff Frequency
Fc2  = 1000;     % Second Cutoff Frequency
flag = 'scale';  % Sampling Flag
% Create the window vector for the design algorithm.
win = blackmanharris(N+1);

% Calculate the coefficients using the FIR1 function.
b  = fir1(N, [Fc1 Fc2]/(Fs/2), 'bandpass', win, flag);
Hd = dfilt.dffir(b);
