2.49 Consider the following sequences: (i) xi[n] =38[n-2]-28[n+1], (ii) x2[n] = 58[n-3]+28[n+1], (iii) h [n] = -8[n+2]+48[n]-28[n-1], (iv) h2[n] = 38[n 4] + L.58[n 2] 8[n+ 1]. Determine the following sequences obtained by a linear convolution of a pair of the above sequences: (a) yi[n] = x1 [n] hi[n], (b) y2[n] = x2[n]Oh[n], (c) y3[n] = [n] = x1 x1[n]@h2[n]. (d) y4[n] = x2[n] hi[n]. 2.49 Consider the following sequences: (i) xi[n] =38[n-2]-28[n+1], (ii) x2[n] = 58[n-3]+28[n+1], (iii) h [n] = -8[n+2]+48[n]-28[n-1], (iv) h2[n] = 38[n 4] + L.58[n 2] 8[n+ 1].
