A Tool for Balance Control Training Using Muscle Synergies and Multimodal Interfaces

Algorithm 1

Fs = 20000;        % Sampling Frequency

Fpass = 3;        %    Passband Frequency

Fstop = 10;       % Stopband Frequency

Apass = 10;       %  Passband Ripple (dB)

Astop = 100;       %    Stopband Attenuation (dB)

match = ‘stopband’;  % band to match exactly

% construct an FDESIGN object and call its BUTTER method.

h = fdesign.lowpass (Fpass, Fstop, Apass, Astop,  Fs);

Hd = design(h, ‘butter’, ‘MatchExactly’,match);

y = filter(Hd, IoutTerefes);
