7 pts) Consider an FSK system where bits 1 and 0 are transmitted using signals si(t) and s2(t) 2Eb 2Eb where θ1 and 02 are the phases of the two signals. (a) (3 pt) Find the correlation between the signal s1(t) ard salt), i.e., find oin(t)s2(t)dt. b) (2 pt) Assuming non-coherent carriers, i.e., θ|メ02, state the condition for which the correlation derived in part (a) goes to zero. (c) (2 pt) Repeat part (b) for the case where the carriers are coherent, i.e., θ1: θ2.
