Understanding the Z-Transform

SOLVED: 175. Describe the effect of each of the following geometric transformations. To generate and test your hypotheses, transform some simple points. a) T(x,y) = (-3x,-3y) b) T(z,y) = (y,x) c) T(x,y) = (y,-x) d) T(x,y) = (0.61x 0.8y, 0.8x 0.6y)176. (Continuation) Each transformation takes the general form T(x,y) = (ax by, cx dy) using suitable constants a, b, c, and d. For example, a = -3, b = 0, c = 0, and d = -3 in part (a). What are the values of a, b, c, and d for the remaining exam
