    I have a quation for communication[Radio] (signal) . It is a period and
    autocorrelation
    signal X(t) .
    The equation is Rx(tau)=5-3 l tau l ,l tau l<=1 & Rx(tau)=2 , l tau
    l>1.
    Please To solve the power of direct current (DC) from the X(t)?
    The answer is 3 or 5 W.Why?
    Thank you!!

    _Always_ include units in your equations. 2 x 3 does not equal 6 watts,
    it just equals 6.

    Your equations are a bit too cryptic to make out. I wish I knew a good
    ASCII-art reference for clear equations, but I don't. The math
    newsgroups use LaTex syntax, which works pretty well.

    Have you asked your professor or your class's teaching assistant for
    help? Fellow students?
