% Elliptic Lowpass filter designed using FDESIGN.LOWPASS.

% All frequency values are in Hz.
Fs = 1024;  % Sampling Frequency

Fpass = 100;     % Passband Frequency
Fstop = 125;     % Stopband Frequency
Apass = 1;       % Passband Ripple (dB)
Astop = 80;      % Stopband Attenuation (dB)
match = 'both';  % Band to match exactly

% Construct an FDESIGN object and call its ELLIP method.
h  = fdesign.lowpass(Fpass, Fstop, Apass, Astop, Fs);
Hd = design(h, 'ellip', 'MatchExactly', match);
set(Hd, 'Arithmetic', 'double');
