1.37. An important concept in many communications applications is the correlation be- tween two signals. In the problems at the end of Chapter 2, we will have more to say about this topic and will provide some indication of how it is used in practice. For now, we content ourselves with a brief introduction to correlation functions and some of their properties. Let x(t) and y(1) be two signals; then the correlation function is defined as - L. b1,(1) = x(1 + T)y(7)dT. The function ,u(1) is usually referred to as the autocorrelation function of the signal x(t), while oy(t) is often called a cross-correlation function. (a) What is the relationship between 4,y(1) and øy»(1)? (b) Compute the odd part of øx:(1). (c) Suppose that y(t) = x(t + T). Express ,,(1) and Þyy(1) in terms of p«(1).
