Consider the line impulses where - < m < and - < n < . (a)

Question:

Consider the line impulses

r[m, n] = > ö[0, n – k], y[m, n] = 8[0] s[m – ( %3D k=-00 l=-00


where -∞ < m < ∞ and -∞ < n < ∞.

(a) Draw the line impulses x[m; n] and y[m; n]. Determine if they are separable.

(b) Consider the product z[m; n] = x[m; n]y[m; n]. Express z[m; n] in terms of unit-step functions u14[m; n], with support in the first and fourth quadrants, and u23[m; n], with support in the second and third quadrants.
