A generator (which may be represented by an emf in series with an inductive reactance) is rated 500MVA, 22kV. Its Y-connected windings have a reactance of 1.1 p.u. Find the ohmic value of the reactance of the windings.
Describe the functionality of the above DFSM using transition tables. Consider that the system starts always from state B. What happens if the system will start from another state - say A?
At the instant shown, car A has a speed of 20km/h, which isbeing increased at a rate of 300km/h2 as the car entersan expressway. At the same instant, car B is decelerating at250 km/h2 while traveling forward at 100 km/h.
A controlled three-phase six-pulse AC/DC converter is supplied with 60 Hz voltage of the line-to-ground RMS value U = 240 V with the output current ideally filtered by an inductor. The maximum DC power of the converter (Pd)max = 50 kW.
A newly planted tree is supported against the wind by a rope tied to a stake in the ground. The force of the wind, though distributed over the tree, is equivalent to a single force F. Find the tension in the rope
a) Draw the state diagram b) Draw the schematic for the logic to implement this circuit using Inverters, AND gates, OR gates and D flip flops. Use the reverse side and additional sheets if needed.
a) What is the minimum sampling frequency b) Specify the number of uniform quantization steps needed and the channel null bandwidth required, assuming that the peak signal-to-noise ratio at the receiver output needs to be at least 30 dB
What bit pattern (after you remove the beginning and ending flags and any stuffed bits) will the receiver pass on for higher level processing?
Addition of two numbers in IEEE 754 format A) a=3f200000, b=be600000 B) a=3f200000, b=ff800000 C) a=01100000, b=80e00000
A silicon sample at T = 300 K contains an acceptor impurity concentration of \(N_{A}\) = 1016 cm-3. Determine the concentration of donor impurity atoms that must be added so that the silicon is n-type and the Fermi energy is 0.20 eV
A transmission line has the following per-unit-length parameters: L = 0.5 H/m, C = 200 pF/m, R = 4.0 /m, and G = 0.02 S/m. Calculate the propagation constant and characteristic impedance of this line at 800 MHz. If the line is 30 cm long
A system samples a sinusoid of frequency 480 Hz at a rate of 100 Hz and writes the sampled signal to its output without further modification. Determine the frequency that the sampling system will generate in its output.
For the function G(x) = x + 32 / x^2 A) Determine the relative minimum of G B) Describe the concavity for all values of x except zero
