		CCD signal processing

Types of filters which can be implemented easily now
  (a)non-recursive filters--need stable on-chip feedback amplifiers
  (b)filters defined  by the  arithmetic operations  of addition  and
  mult by const need multipliers
Thus, an  edge operator  is ok (uses  only mult  by const) but  cross
correlation is  not ok; that requires  the multiplication of elements
from two shift registers

The design for an edge operator follows:
