can you please solve the questions thanks a lot a) i) Sketch the sequence x[n] = cos (n. π/2) plotted against 'n' (the sketch shouldonly go from n = -2 to n = +3). State whether x[n] is even or odd and why.ii) Find the output sequence, y[n], if x[n] = (1/2)" and h[n] = ½, 1⁄2, 0, 0...overthe period n=0 to n=2 by using convolution.iii) Draw the system model corresponding to the Linear Difference Equation (LDE):y[n] = a.(2.x[n] - x[n-1])Is this system stable? Is it recursive?

Given Data: A sequence of xn=cos nπ2, -2≤n≤3 The input and impulse sequences of, xn=12n hn=12,…
