Q31.
____ ensures data integrity.

a.

INFOSEC

b.

TRANSEC

c.

Network support

d.

Source coding

Discuss
Answer: (a).INFOSEC Explanation:Information security operations such as authentication and stream enciphering ensure data integrity. Further, authentication reduces fraud and stream enciphering assures privacy.
Q32.
____ device allows inclusion of new hardware components without external physical intervention.

a.

Configurable

b.

Plug and Play

c.

DSP

d.

ASIC

Discuss
Answer: (b).Plug and Play Explanation:Plug and Play device facilitate the inclusion of hardware components without physical configuration or external user intervention. A challenge posed by plug and play modules is the definition of interface points.
Q33.
Which of the following is not characteristic of a plug and play module?

a.

Compatibility

b.

Configurability

c.

Controllability

d.

Predictability

Discuss
Answer: (b).Configurability Explanation:The plug and play module must be compatible with radio environment. It must be controllable under defined module and have predictive usage of resources.
Q34.
____ must preserve radio service-defining properties of the system.

a.

Module control

b.

Module composition

c.

Joint control

d.

Joint composition

Discuss
Answer: (b).Module composition Explanation:Module composition must preserve radio service-defining properties of the system. It prevents erroneous results from being generated on control commands. It also ensures proper consumption of computational resources.
Q35.
Digital translation of a baseband signal into an IF is an example for ____

a.

continuous-time point operation

b.

continuous-frequency point operation

c.

discrete-time point operation

d.

discrete-frequency point operation

Discuss
Answer: (c).discrete-time point operation Explanation:Digital translation of a baseband signal into an IF is an example for Discrete-time point operation. Discrete-time point operation involves the multiplication of discrete time-domain baseband waveform by a discrete reference carrier to give sampled in-phase IF waveform.
Q36.
Which among the following is not a property of offline software support?

a.

System analysis

b.

Air interface modes

c.

Re-hosting of hardware

d.

Signal processing

Discuss
Answer: (b).Air interface modes Explanation:System analysis, re-hosting existing software on new hardware, and advanced signal processing are properties of offline software support. It is achieved by prototyping and linking with channel processing streams. It also allows debugging of algorithms.
Q37.
How are the bits at the output of INFOSEC (towards source) stage referred?

a.

Black bits

b.

Shielded bits

c.

White bits

d.

Clear bits

Discuss
Answer: (d).Clear bits Explanation:The bits at the output of INFOSEC are referred to as clear bits. These are then operated on to give network or source bits. Network bits comply with network protocols and the source bits are passed to source decoder.
Q38.
_____ stream characterizes radio surrounding usage in terms of time, frequency, and space.

a.

Online adaption

b.

Offline adaption

c.

Environment management

d.

Real-time channel processing

Discuss
Answer: (c).Environment management Explanation:Environment management stream characterizes radio surrounding usage in terms of time, frequency, and space. It also includes channel identification and estimation of channel interference levels.
Q39.
Digital-access bandwidth is approximately double of the sampling rate of the ADC in the isochronous subscriber signal-processing path.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Digital-access bandwidth is approximately half of the sampling rate of the ADC in the isochronous subscriber signal-processing path. Digital access bandwidth and degree of flexibility are two important parameters of a software defined radio.
Q40.
The introduction of plug and play modules in software defined radio involves partitioning of functions and components

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:A partition should ensure clear matching of functions to components. The physical interfaces among components must correspond to logical interfaces among functions.
