ABSTRACT:
A CCD comb filter is provided employing a basic block having a first, a second and a third delay line wherein particular mixing of the signals from the delay lines results in three outputs having a desired ratio. This basic block is utilized to construct a contour compensation circuit, a drop-out compensation circuit and a 3H delay line. The basic block is versatile and can be utilized for constructing other devices also.
