Suppose s(t) is an angle modulated signal with message signal m(t), peak frequency deviation Af = 3000 Hz, and modulation index 3 = 4. Assume m(t) ranges from - a to a. Further suppose s(t) is an FM signal, and suppose the message signal is changed to m' (t) = m(t) + a. What is the new peak frequency deviation? What is the new modulation index? Now suppose s(t) is a PM signal, and again suppose the me changed to m' (t) = m(t) + a. What is the new peak frequency deviation? What is the new modulation index? Hz ge signal is Hz
