Abstract:
This paper discusses usual methods to 2-D sing leside inverse-Z t ransform. The 2-D sequences are devided into several kinds: seperate, leng th finite, and other s; and the given methods ar e 1-D method, part ial-der iv at ive method, 2-D combined convolut ion, 2-D contour integral and 2-D deconvolut ion method. Because inverse-Z t ransform in the case of 2-D is much more complicated than that in 1-D, w hich appears in 2-D converg ent region o r tw o variates factorizat ion or teriable computat ions, etc. So the methods g iv en in this paper can be used to g et some simple inverse-Z t ransform. The part ial-derivat ive metho d and deconv olution method are o f pract ical use.
