86/87h Write/Read B1 Filter Coefficients
Cxy = 0 or 1 in the command above corresponds to Cxy = +1 or −1, respectively, in the equation below.
The Z-transform equation for the B filter is defined as:
The coefficients for the FIR B section and the gain of the IIR B section are defined as:
For i = 2 to 10,
The feedback coefficient of the IIR B section is defined as
Refer to Command 96/97h for programming of the B
