You must show all the work and all sequence networks needed to get these numbers.
For the radial power system shown in table, calculate the line-to-ground fault current flowing in each of the CBs for faults at each of the buses. The system data are given in the accompanying table. Also determine the corresponding faulted phase voltage, assuming that the generator is ideal, with a terminal voltage of 1.0 pu.

The FM input to a PLL demodulator has an unmodulated center frequency of 10.7 MHZ. (a) To what frequency must the VCO be set (b) From which circuit is the recovered modulating signal taken
The turns ratio (n3/n1) is chosen such that the converter produces the required output voltage at a transformer duty cycle of D=0.4. For each case determine numerical values for the turns ratio n3/n1 and for the efficiency.
Using a shorted stub to match load, what is the lenght of the line where the normalized input Y is 1 + jb . If the characteristic impedance of the shorted line is 40 ohms, what is the length of the stub length.
Show that H(s) is invertible with an LTI inverse that is causal and stable (meaning, we can implement the inverse system) if and only if all poles and zeros of H(s) are strictly in the left half plane. We call such an H(s) minimum phase.
How would you implement in the assembler a logical-shift-left(LSL) pseudo-operation for a machine that didn.t have this particular instruction Be sure your LSL instruction can shift up to W-bits where W is the machine word size in bits.
Find the Fourier transform X(eiω) of x[n]. Find the N-point DFT X [k] of the finite-length sequence x[n). Find the DFT of x[n] for the case ω0 = 2πk0/N, where k0 is an integer
The strength of longitudinal joint in Fig. 1-17 is 33 kips/ft, whereas for the girth is 16 kips/ft. Calculate the maximum diameter of the cylinder tank if the internal pressure is 150 psi.
A 110 pF capacitor and a 440 pF capacitor are both charged to 2.2 kV. They are then disconnected from the voltage source and are connected together, positive plate to positive plate and negative plate to negative plate.
Determine the expression for the frequency response H(O) of a causal IIR LTI discrete-time system characterized by the input-output relation y[n]=x[n]-ay[n-R], |a|
Write the 9S12DP256 assembly language instructions below a programmer could use to copy the 3rd variable from a 10-byte array into Accumulator B.
Is the second law satisfied? Will this refrigerator still satisfy the second law if its coefficient of performance is 6?
Explain why the low value (0) for the 'output' of a digital logic gate is lower than the low value for the 'input' of a digital logic gate (This is the case for CMOS and Bipolar logic). Look at a specsheet.
