Two-dimensional digital ixj filter of rang, r<i, implemented as degenerated rxj digital filter |
摘要 |
A signal input in a raster scan format is entered into one-dimensional digital filters. An output of the one-dimensional digital filter is multiplied in a multiplier. Outputs of one-dimensional digital filters are provided to delay circuits to generate a time delay in a direction perpendicular to the raster scan direction. The output of the multiplier and the outputs of the delay circuits are added by adders. A one-dimensional digital filter of the vertical direction is decomposed in a manner more simple than in the horizontal direction to reduce delay time between input and output.
