Thanks for you read! My project use the biquad funtion,and i generate the coeffs using the matlab!
1,I use fdatool, design a filter!
2,exprot the coeffs
In my mind the [b0, b1, b2] = 0.7133126985410756*[1, 0, -1] , [a0, a1, a2] = [1, -1.9962346947976051, 0.99625876838666028 ]
and the other also like this!
3,I read the help of the biquad
then i give the[ -0.7133126985410756*,0,0.7133126985410756,0.99625876838666028,-1.9962346947976051] to [B2,B1,B0,A2,A1]]
4,But the result is not right,
so i want anyone could pointe out the mistakes ,and give me some advise!
