trans-
verse filter implementation

chosen, each of these transverse filters can be imple-
mented using the structure shown in Figure 37.15
above, which employs four registers and four adders.
The [2, 8, 12, 8, 2] filter is identical, but has its final
sum shifted left one place to accomplish the multiplica-
tion by 2.
The 2-line spatial filter of Figure 37.13 can be imple-
mented using a linestore, two [1, 4, 6, 4, 1] transverse
filters, and an adder, as shown in Figure 37.16 below.
The 3-line spatial filter of Figure 37.14 can be imple-
mented ...
