hi
I must use a IIR filter with x1 and x2 as inputs and y1 and y2 as outputs.
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.
