Figure 6-1: nCH Filter Dialog
Description of the controls pictured in Figure 6-1 follows:
Filter Size
Used to set the number of FIR filter taps in the adaptive filter. Filter size is
indicated both in taps (filter order) and in milliseconds. Minimum filter size is 16
taps, but can be set as high as 4500 taps depending on the channel
configuration and system bandwidth.
Adapt Rate
Used to set the rate at which the adaptive filter adapts to changing signal
conditions (mathematically known as Mu). A Mu of 1 x 2
-18
provides very slow
adaptation, while a Mu of 5884 x 2
-18
provides fastest adaptation. Slower adapt
rates take longer to reach a solution or to adapt to changing signal
characteristics. Faster adapt rates are more susceptible to filter crashes.
Delay
Sets the amount of delay to be applied to the input. The delay can be applied to
either the primary or the reference channel(s). Delay is indicated both in
