1) Following mathematical function, explain the basic correlation function. This function may accept 10 input samples(x1,x2) to produce output. Detail explanations as shown below. N-1 R12 = *{ x2(n)xz(n) n=0 Where, N X1 X2 - Total Number of samples - Samples 1 - Samples 2 - Integer number n n The followings example shows the calculation for the 9 input samples 1 2 3 4 5 6 7 8 4 2 -1 3 -2 -6 -5 4 -4 1 3 7 4 -2 -8 -2 9 5 1 X2 = R12 (4 x4 +2 x 1+-1% 3+3 x 7+-2 x 4 +-6 X-2+-5X-8 + 4 x -2 + 5X1)=5
