Consider the following register transfer statements for two 4-bit registers R1 and R2.

PT: R1← R1^ R2

Every time that variable T = 1, either the content of R2 is added to the content of Rl if

x = 1, or the content of R2 is transferred to R1 if x = 0. Draw a diagram showing the

hardware implementation of the two statements. Use block diagrams for the two 4-bit

registers, a 4-bit adder, and a quadruple 2-to-1-llne multiplexer that selects the inputs

to R l . In the diagram, show how the control variables x and T select the inputs of the

multiplexer and the load input of register R1.

suppose the joint P.D.F of(X,Y) is given by 

f(X,Y) = x²+1/3(xy) , 0<=x<=1 , 0<=y<=2 and 0 elsewhere

a) compute i) P(X>1/2), ii) P(Y<X), iii) P(X+Y>1) , iv) (Y<1/2 | X< 1/2)

A rod, which tapers uniformly from 40 mm diameter to 20 mm diameter in a length of 400 mm,

is subjected to an axial tensile load of 5000 N. If E = 2.1 × 105 N/mm2

, find the extension of the

rod.

In the optical transmission, a rectangular waveguide with a = 2b = 4.8 cm is filled with Teflon (r = 2.11, loss tangent of 3 X 10-4) is used. Assume that the walls of the waveguide are coated with gold (σc = 4.1 X 107 S/m) and that a TE10 wave at 4 GHz propagates down the waveguide. Compute the value of attenuation due to conduction and ohmic losses.
