Design a circuit of General register organization in which 4 registers are there from R0 to R3. (a) Perform the following microoperation and explain the operation in the steps through the diagram properly: - AND R3 ,R3 ,R1 . (b) Explain the control word as per the register configuration given above.

Five batteries are connected in parallel to supply a certain load. Each battery consist of 12 cells in series. Each cell has an emf of 2V and the internal resistance of each cell is 0.15Ω. What should be the resistance of the load so that the total power consumed is 384 watts?

A cable is suspended between two supports at the same elevation 250m high and 500 m apart. The load is 500 kg per horizontal meter including the weight of the cable. The sag of the cable is 50 m. calculate the total length of the cable.

) A 100 MVA, 13.8 kV, 60 Hz, Y-connected 3-phase generator with Xd ’’=Xd ’=20% is connected to a 13.3/220 kV, 100 MVA, ∆-Y connected transformer and to the 3-phase load of 100 MVA 0.8 p.f. lagging is connected to the transformer secondary as shown in the figure. The leakage reactance of ∆-Y transformer is 10%. The L-L voltage at the load Page 5 of 5 terminals is 220 kV. A 3-phase short-circuit occurs at the load terminals. Find the generator transient current including load current.  

a one dimensional steady flow is given by the following velocity;

"u=\\frac{2}{\\gamma+1}(\\frac xt-a_0)"

And density field;

"\\frac{\\rho}{\\rho_0}=(\\frac{\\gamma -1}{\\gamma+1}\\frac xt\\frac{1}{a_0}+\\frac{2}{\\gamma+1})^{\\frac{2}{\\gamma-1}}"

a)Calculate the substantial change of density.

b) check the validity of the continuity equation

"\\frac{D\\rho}{Dt}+\\rho\\frac{\\partial u}{\\partial x}=0"

for this flow field.

A compact disc (CD) records audio signals digitally by PCM. Assume audio signal's bandwidth to be 15 kHz. If signals are sampled at a rate 20% above Nyquist rate for practical reasons and the samples are quantized into 65,536 levels, determine bits/sec required to encode the signal and minimum bandwidth required to transmit encoded signal.
