An angle-modulated signal with carrier frequency ωc=2πx106 is described by the equation φEM(t)=10cos(ωct + 0.1sin2000πt).
a) Find the power of the modulated signal.
b) Find the frequency deviation Δf.
c) Find the phase deviation Δφ.
d) Estimate the bandwidth of φEM(t)
State briefly the consequences of opening the secondary of a current transformer when it is in service. State the precaution to be taken should disconnection be necessary.
Design a circuit to provided a positive voltage whose magnitude is equal to the acceleration (revolutions pre minute) of the wheel. Assume the velocity sensor's output 1 mV/rpm, and the wheel rotates at less than 3500rpm.
Reduce the two functions given below and implement them using fewest 8x2 ROM's. Draw a neat labeled diagram showing interconnection between the ROM's address and data lines, and content of each ROM.
Describe how you would use the voltage follower so the output load voltage (as measured with a scope probe) agrees with the value shown on the function generator front panel independent of load impedance. Describe any compromises or inefficiencies..
what do u mean by term slip of three phase induction motor calculate the slip of 4-pole induction motor running at 1470 rpm while bieng connected to a 50 hz three phase source
For each of the sinusoidal source functions, determine the complex exponential source that has the given source as its imaginary part. Determine the phasor representation of each of the sinusoidal source functions.
Design a combinational logic circuit which has one output Z and a 4-bit input ABCD representing a binary number. Z should be 1 iff the input is at least 5, but is no greater than 11. Use one OR gate (three inputs) and three AND gates
A three-phase, wye-connected, 20-MW load of power factor 0.866 lagging is to be supplied by a transmission line at 138 kV. It is desired that the line losses not exceed 5 percent of the load. If the per-phase resistance of the line is 0.7 Ohm
An electron beam coming from an electron gun consists of electrons that are uniformly distributed within a cylindrical region of space having a radius a = 1 [mm]. The axis of the cylinder is along the z axis, and the electrons are moving
