....lter. Then our design method attempts to meet the following requirements: 1. The derivative lters must be good approximations to the derivative of the pre lter. That is, for a derivative along the x axis, we would like Fleet and Langley have designed recursive lters for these purposes [39]. jk 1 B(k) D(k) where k 1 is the component of the frequency coordinate in the x direction. 2. The lowpass pre lter should be symmetric, with B(0) 1. 3. For computational eciency and ease of design, the pre lter should be separable. In this case, the derivatives will also be ....
