FIR Taps settings
1-4
Number of FIR Taps for each pair of output channels (i.e.. Output 1&2, output 3&4, output 5&6, output 7&8.)
The sum of all taps cannot exceed 1500 and maximum taps per pair is 1200.
(Parameters 5-8 are also available for XD series v5.xx and v6.xx. The FIR filters have been changed to dual
channel structure in v7.xx.)
For FIR filters, the higher the Taps the higher the slope in dB for the same frequency, or the lower the
frequency the FIR can handle for the same slope. Generally speaking, higher frequencies require smaller
number of Taps, and lower frequencies require a higher number of Taps.
