A solid aluminum sphere of radius 3 in. is welded to the end of a 6-in.-long rod AB of negligible mass which is supported by a balland-socket joint at A. Knowing that the sphere is observed to precess about a vertical axis at the constant rate of 60 rpm in the sense indicated and that rod AB forms an angle ß = 30° with the vertical, determine the rate of spin of the sphere about line AB.
Determine the Intelligence frequency, carrier frequency, Modulation index, Carrier power, total power in FM signal and power in each sideband.
