Question 2

In BJT Common Base Configuration, in saturation region:

Question 3

The oscillation frequency of the system with the characteristic equation
S6 + 2S5 +3S4 + 4s3 +3s2 + 2s +1=0 is

Question 4

If 512 kB memory space is to be provided, then find the amount of 64k x 1 RAM chips needed?

Question 5

Statement (I) : Lead compensation is used to improve system stability margins.
Statement (II) : Lead compensation achieves the desired result through the merits of its phase lead contribution.

Question 6

Statement (I): On chip Cache memory is used for temporary storage of commonly used code/data copied from the main memory.
Statement (II): Provision of Cache memory eliminates the need for the processor to go off the chip to access the main memory thus improving the processor performance.

Question 7

Consider the following statements:
A multiplexer
1) selects one of the several inputs and transmit it to a single output.
2) routes the data from a single input to one of many outputs.
3) converts parallel data into serial data
4) is a combinational circuit
Which of the above statements are correct?

Question 8

Which of the following are the properties of TEM mode in a lossless medium ?
1) Its cut-off frequency is zero.
2) Its transmission line is a hollow waveguide
3) Its wave impedance is the impedance in a bounded dielectric.
4) Its phase velocity is the velocity of light in an unbounded dielectric.
Select the correct answer using the code given below:

Question 9

Hexagonal Close Packed Structure will not include:

Question 10

A resistance strain gauge with gauge factor of 3 is cemented to a steel member subjected to a strain of 2 x 10-6. If the original resistance is 100 Ω, what is the change in resistance?
