Explanation: We know that, the correlation of two signals x(n) and y(n) is Let x(n)=y(n)=> 6. What is the energy sequence of the signal ax(n)+by(n-in terms of cross correlation and auto correlation sequences?
A. a2rxx(0)+b2ryy(0)+2abrxy(0)
B. a2rxx(0)+b2ryy(0)-2abrxy(0)
C. a2rxx(0)+b2ryy(0)+2abrxy(1)
D. a2rxx(0)+b2ryy(0)-2abrxy(1)
