Relation between in and out is : y1[n] = (1/k2) * (x1[n] - y1[n-1]) + (1/9 * k1) * (x2[n-1] - y2[n-2]) y2[n] = (1/k2) * (x2[n] - y2[n-1]) + (1/k1 ) * (x2[n-1] - y2[n-2]) I need some guide to analyze this filter. How k1 and k2 determine filter response ? How i can choose proper sampling frequency ? Maybe a .m file from Matlab could be very useful. Thanks for your support.
