Use Matlab to:
a. Find the sub transient per-phase equivalent circuits of this power system for positive-, negative- and zero-sequence component.
b. Find the subtransient fault current at the fault found at the location indicated by X for:
i) A symmetrical three-phase faultii) A single line-to-ground faultiii) A line-to-line faultiv) A double line-to-ground fault
(A student will solving for the transient fault line current for two (2) types of fault to be specified by the lecturer).
A digital signalling system is required to operate at 38.4 Kbps. If a signal element encodes a 8-bit word, what is the minimum required bandwidth of the channel. what signal to noise ratio is required to achieve the desired capacity on bandwidth t..
Write an HDL behavioral description of a four-input priority encoder. Use a four-bit vector for the D inputs and an always block with if-else statements. Assume that input D[3] has the highest priority.
what load should be connected to terminals a-b of the circuits in Fig. 11.51 so that the maximum power is transferred to the load?
Design a multiplexer which has four input lines, two controllines, and one output line and a demultiplexer which has one input line, two control lines, and four output lines using truth tables and k-maps.
What RF bandwidth is required to send the data using QPSK? If the RRC filters in the transmitter and receiver are replaced with ones that have ? = 0.20, what are the new RF bandwidths in parts (a) and (b)?
Prove that the system does not satisfy a 5-dB gain margin. The plot represents a proportional gain of 5.0. What gain will make the system satisfy a 5-dB gain margin? What is the phase margin?
Determine the conductivity of silicon at T = 300 K if it is doped with donor impurity atoms at a concentration of 1.25*1016 cm-3. Assume that the electron and hole mobilities are 1350 cm2 / V-s and 480 cm2 / V-s, respectively.
If the unit interval is equal to 1 ns, what is the expected BER associated with this system at a normalized sampling instant of 0.5 UI?
Determine the frequency at which a 1-µF capacitor and a 10-mH inductor will have the same reactance.
Suppose mH,(N) = N + 1, so dva = 1. You have 100 training examples. Use the generalization bound to give a bound for Eaut with confidence 90%. Repeat for N = 10, 000.
The 3-bit flash A/D converter in Figure has a reference voltage of VREF = 3.3 V. The 3-bit output is 101. What is the range of vA that produces this output?
a. Functionally, how do closed-loop systems differ from open-loop system b. State one condition under which the error signal of a feedback control system would not be the difference between the input and the output.
