See note under COP Command 2 on
Note:
Z6 is used for IIR filter scaling only. Its value is typically greater than zero but less than or equal to one. The input to the IIR filter section is first
increased by a gain of 1/Z6, improving dynamic range and avoiding truncation limitations through processing within this filter. The IIR filter output
is then multiplied by Z6 to normalize the overall gain. Z5 is the actual IIR filter gain value defined by the programmed coefficients, but it also
includes the initial 1/Z6 gain. The theoretical effective IIR gain, without the Z6 gain and normalization, is actually Z5/Z6.
COP 5. Write/Read B1 Filter Coefficients (B-FIR)
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:
