Q21.
____ is a measure of good information received.

a.

Latency

b.

Data rate

c.

Bit rate

d.

Throughput

Discuss
Answer: (d).Throughput Explanation:Data rate is a measure of rate at which data arrives regardless of transmission errors. Throughput is the measure good information available at the receiver.
Q22.
Which among the following is an objective that influences throughput?

a.

Bit error rate

b.

Bandwidth

c.

Spectral efficiency

d.

Signal to interference ratio

Discuss
Answer: (a).Bit error rate Explanation:Bit error rate is an objective for that influences throughput. Modulation type, symbol rate, and number of bits per packet are the monitor parameters. Throughput does not have any meters that influence the result.
Q23.
Gaussian minimum shift keying is based on frequency shift keying.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Gaussian minimum shift keying involves Gaussian filtering the modulating signal and passing it through frequency modulator. The second method uses quadrature modulator otherwise known as I-Q modulator.
Q24.
Minimum shift keying experiences phase discontinuities.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Minimum shift keying does not experience phase discontinuities because frequency changes occur at the carrier zero crossing points. This is expressed by setting the modulation index to 0.5.
Q25.
In multiobjective analysis, ____ function is used for selection.

a.

subjective

b.

single valued

c.

utility

d.

set

Discuss
Answer: (c).utility Explanation:In multi objective analysis, single utility function involves combining several objectives into a single number. Ranks are assigned to solutions. The solution that maximizes utility function is selected.
Q26.
The significance of weighted sum utility function approach is that the ____ can be determined.

a.

optima at extreme edges

b.

optima at centre

c.

concavity at extreme edges

d.

concavity at centre

Discuss
Answer: (a).optima at extreme edges Explanation:The weighted sum approach involves computing the sum of product of objective function and the weight assigned to them. The significance of weighted sum utility function approach is that the optima at extreme edges can be determined.
Q27.
Cobb Douglas function is otherwise called ____

a.

linear function

b.

weighted sum function

c.

logarithmic function

d.

linear logarithmic function

Discuss
Answer: (d).linear logarithmic function Explanation:Cobb Douglas function is otherwise called linear logarithmic function. It is an advanced version of weighted sum approach. The result is shaped by the logarithmic function. The logarithmic function adds convexity to the optimisation curve.
Q28.
____ defines the amount of change constituted by the substitution of one parameter by another parameter.

a.

Rigidity

b.

Elasticity

c.

Replaceable

d.

Replicable

Discuss
Answer: (b).Elasticity Explanation:Elasticity defines the amount of change constituted by the substitution of one parameter by another parameter. A value of 1 indicates perfect substitution. Constant elasticity by substitution does not require independent input value and is suitable for multi objective analysis.
Q29.
Utility function is an example of ____

a.

no preference method

b.

a post priori method

c.

interactive method

d.

a priori method

Discuss
Answer: (d).a priori method Explanation:A priori method requires setting up of certain amount of desired traits before optingthe solution process. When no desired traits are specified in multi objective optimisation, it is regarded as no-preference method.
Q30.
____ builds a matrix with ____ assigned to columns and ____ assigned to rows.

a.

Multiple single objective Pareto sampling, elasticity, weights

b.

Repeated single objective, elasticity, weights

c.

Multiple single objective Pareto sampling, objectives, ranks

d.

Repeated single objective, objectives, ranks

Discuss
Answer: (c).Multiple single objective Pareto sampling, objectives, ranks Explanation:Multiple single objective Pareto sampling calculates all objectives for each member of the population. A matrix is built with columns representing the objectives, and the rows represent individual rank for each objective.
