Webshifted one place to the right. The general term of this shifted sequence is v n = (n−1)2 n = 1,2,3,... Similarly the sequence {w n} = {0,0,1,4,9,16,25,...} has general term w n = ˆ (n−2)2 n … Webz −1. If Y(z) = X∞ n=0 y nz −n denotes the z-transform of the sequence {y n} that we are seeking then X∞ n=0 y n+1z −n = z Y(z)−zy 0 (by the left shift theorem). Consequently (2) can be written z Y(z)−zy 0 −3 Y(z) = 4z z −1 (3) Equation (3) is the z-transform of the original difference equation (1). The intervening steps have

WebCompute the Z-transform of exp (m+n). By default, the independent variable is n and the transformation variable is z. syms m n f = exp (m+n); ztrans (f) ans = (z*exp (m))/ (z - exp (1)) Specify the transformation variable as y. If you specify only one variable, that variable is the transformation variable. The independent variable is still n.
