Starting from an initial value of R in Hex is A4 determine the sequence of binary values in R  after a logical shift-left, followed by a circular shift-right, followed by a logical shift-right and a circular shift-left. explain through the proper diagrams

Design a circuit that would be able to shift bits but also store them for a duration of time. Explain what are the technicalities of such a circuit. 

Consider a fused silica single-mode fiber that is 1 km long. Find the material dispersion component of the pulse spread if Delta lamda is 3.0 nm and the operating wavelengths are 800 nm, 900 nm, 1300 nm and 1500 nm.

Various resistors

R1 Brown-Red-Black-Silver

R2 Brown-Gray- Brown-Gold

R3 Brown-Black-Red-None

R4 Red-Red-Brown-Red

R5 Brown-Red-Red-Gold

Connect an impedance Z1 = (10,516+j6,571) ohms in series to V1 = 224<150 V to form the first branch and the second branch is Z2 = (11,031-j11,031) ohm in series to V2 = 248<350 V. The third branch has only impedance Z3 =(12,99+j7,5) ohms. These three branches are connected in parallel. (You may be required to calculate the values of inductance(L) or capacitance(C) if necessary.)

• Draw the circuit (5)

• Calculate the current flowing through each branch using superposition theorem

Explain any difference between the measured and the calculated values.

A 12 ohm resistor is connected in parallel with series combinations of resistors of 8 and 16 ohms. If the drop across the 8 ohm resistor os 48 volts, determine the total impressed emf and total current.

Three resistors A,B , and C are connected in series to a 117 volt source . If RA= 64 ohms , and EB = 40 volts when the current is 0.5 amp , calculate the resistors RB and RC

to determine the resistances of the three resistors . A,B, and C the following procedure is followed. Ra and Rb are connected in series and emf 21 volts is impressed for a current of 1 amps, Rb and Rc are next connected in series and emf 27 volts is impressed for the same adjusted current , finally Rc and Ra are connected in series emf of 24 volts is impressed for the same adjusted current . What are the ohmic values of A, B and C?
