qUESTION: When will there be a drawback in using a Virtual Memory and why?
Verify that the boundary conditions for the electric and magnetic fields at the interface between two dielectric media lead to the Fresnel equations for the reflection coefficient for both the TE and TM modes.
Convert the following numerical arithmetic expression into Reverse Polish
notation and show the stack operations for evaluating the numerical result.
(2 + 6)[7(3 + 5) + 1]
An instruction is stored at location 200 with its address field at location 201 . The
address field has the value 300. A processor register R1 contains the number 100.
Evaluate the effective address if the addressing mode of the instruction is (a) direct;
(b) immediate; (c) relative; (d) register indirect; Also explain with necessary diagram.
Convert the following arithmetic expressions from infix to Reverse Polish
notation. Also show positions in Stack by possible diagram.
a. P * Q + R* S + T* U
b. A * B + A * (B * D + C * E)
c. M + N * [O * P + Q * (R + S)]
How many characters per second can be transmitted over a 9600-baud line in each of
the following modes? (Assume a character code of eight bits.)
a. Synchronous serial transmission. Also draw timing diagram.
b. Asynchronous serial transmission with two stop bits. Draw timing diagram
c. Asynchronous serial transmission with one stop bit. Draw timing diagram.
Q2/ Estimate the fiber fault location if the time reflected from front pulse is 10 ns
and the reflected from far ends pulse is 15 ns, assume the core material is glass.
38. A 12-ohm resistor is connected in parallel with a series combination of resistors of 8 and 16 ohms. If the drop across the 8-ohm resistor is 48 volts, determine the total impressed emf and the total current.
45. Two equal resistors RA and Rв are connected in parallel and to a 120-volt source. What potential difference exists between the midpoint of RA and a point that is one-third from either end of RB?
Design a transistor fixed bias circuit with VCC = 12V, VBE = 0.7V, β=100 and RC =1KΩ to operate in middle of the Load line (for IC = 6mA), cut off region (for IC = 0.5
mA) and saturation region (for IC = 11.5 mA). Determine the corresponding values of
RB and VCEQ for the three different cases.
