39. Read Error Level Threshold

(8Fh)

40. Write GZ Filter Coefficient

(92h)

RSVD

Reserved. Always write as 0, but 0 is not guaranteed when read.

The coefficient, GZ, is defined as:

The default value after any reset is GZ = 0 hex for a gain of 1.

41. Read GZ Filter Coefficient

(93h)

42. Write Adaptive B Filter Control Coefficients

(90h)

The equations for the decorrelation threshold coefficients are:

The equation for the low level signal threshold coefficient is:

The equation for the digital prebalance threshold coefficient is:
