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

Frequency Modulation

Frequency modulation is a method or process of encoding the data of a specific signal (analog or digital) by modulating the carrier wave frequency according to the frequency of the modulated signal. Modulated signals are nothing more than information or data that should be conveyed after being converted into electronic signals.
