96/97h Write/Read B2 Filter Coefficients (IIR)
This function is described in Write/Read B1 Filter Coefficients (FIR) on
Power Up and Hardware Reset (RST) Values = 0190 (Hex) (B
See note under Command 80/81h on
98/99h Write/Read FIR Z Filter Coefficients (FIR only)
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 Z filter is defined as:
For i = 0 to 5 and 7
Power Up and Hardware Reset (RST) Values = 0190 0190 0190 0190 0190 0190 01 0190 (Hex)
See note under Command 80/81h on
Note:
