Prob. 2
(a) In an FM system it is required that all the modulated signal power be concentrated in the sidebands and no power be transmitted at the carrier frequency.
What is the smallest value that ß can take? What is the power in the first sideband for this value of the modulation index?
(b) A carrier is modulated by two sinusoidal modulating signals so that the FM signal is given by
Dem(t) = Acos(2nfct + Busin2nfit + B2 sin2nfzt)
Show that the modulated signal has sidebands separated from the carrier not only at multiples of fı and of f but also has sidebands as well as separations of multiples of f1 + f2 and fı - f2.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
