This paper discusses a design technique for multidimensinal(M-D) multirate filters which cause no checkerboard distortion. In the first part of this paper, a necessary and sufficient condition for M-D multirate filters to be checkerboard-distortion-free is derived in the frequency domain. Then, in the second part, this result is applied to a scanning line conversion system for television signals. To confirm the effectiveness of the derived condition, band-limiting filters with and without considering the condition are designed and the results by these filters are compared. A reducibility of the number of delay elements in such a system is also considered to derive efficient implementation.
