Angle Modulation: Spectral Characteristics In general, for a sinusoidal message signal, the effective bandwidth of an angle-modulated signal , which contains at least 98% of the signal power, is given by the relation where β is the modulation index and f m is the frequency of the sinusoidal message signal. Let the message signal be given by The effective bandwidth of the modulated signal is given by 2
Angle Modulation: Spectral Characteristics The number of harmonics in the bandwidth (including the carrier) Increasing the amplitude a increases the number of harmonics in the bandwidth of the modulated signal in both cases Increasing f m , has no effect on the number of harmonics in the bandwidth of the PM signal and decreases the number of harmonics in the FM signal almost linearly 3

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
