Examples of Coefficient Set Generation and Loading
Example 3:
Num_h_taps = 9; num_v_taps = 7
;
max_phases = num_h_phases = num_v_phases = 4
Now consider the case where the number of taps in the Horizontal dimension is different
to that in the Vertical dimension. For this case, when loading the coefficients for the
dimension for which the number of taps is
smaller
, each
phase
of coefficients must be
padded with zeros up to the larger number of taps.
Example coefficients are shown in hexadecimal form in
Table 8-5
(horizontal) and
Table 8-6
(vertical).
