Explanation: A third possible representation of a band pass signal is obtained by expressing 14. What is the possible representation of x(t) if xl(t)=a(t)e(jθ(t)) ?
A. x(t) = a(t) cos(2pFct – ?(t))
B. x(t) = a(t) cos(2pFct + ?(t))
C. x(t) = a(t) sin(2pFct + ?(t))
D. x(t) = a(t) sin(2pFct – ?(t))
Answer:A
