 Also the Linear Difference equations of the MixeD filters are of lower dimensionality as compared to normal multidimensional filters which results in simplification of the design and increase in the stability.Multidimensional Digital filters are finding applications in many fields such as image processing, video processing, seismic tomography, magnetic data processing, Computed tomography (CT), RADAR, Sonar and many more.There is a difference between 1-D and M-D digital filter design problems.
