Q. Power efficiency of M-ary FSK increases, since

(A) constellation is densely packed
(B) m signals are non-orthogonal
(C) fixed null bandwidth
(D) m-signals are orthogonal

💬 Discuss

✅ Correct Answer: (D) m-signals are orthogonal

Explanation: in m-ary fsk, all the m signals are orthogonal and there is no crowding in the signal space. hence, power efficiency of m- ary fsk increases with m.
