Q 2(c) [11 Marks] The first 4 sample values of a unit step are as follows: x[n] = 1, 1, 1, 1.... (1) Write down the first 4 terms of its Z-transform. This is known as the open form. (ii) Using the z-transform table, write down the closed form. (iii) Using long division, prove that the closed form is equivalent to the open form. Q 2(d) [6 Marks] Using the z-transform table, determine the z-transform of each of the following signals: (1) x(t) = 3sin(5t) (ii) x(t) = 2e-7cos(3t) =
