Q61.
The error corrected bits are ____ to complete the communication process.

a.

grouped

b.

re-transmitted

c.

parsed

d.

discarded

Discuss
Answer: (c).parsed Explanation:The error corrected bits are parsed to identify the header, address, message, traffic, etc. The expected service is delivered to the user after being processed by various protocol layers.
Q62.
The ____ are converted to ____ by ____ detector/demodulator combination.

a.

bits, symbols, bit

b.

symbols, bits, symbol

c.

bits, symbols, symbol

d.

symbols, bits, bit

Discuss
Answer: (b).symbols, bits, symbol Explanation:The symbols, obtained from down conversion process, are converted to bits by symbol detector/demodulation combination. Matched filter is an example for a detector.
Q63.
Which among the following options have forward error correction integrated into the demodulation process?

a.

Trellis code modulation

b.

Soft decoding

c.

Trellis code modulation and soft decoding

d.

Block codes

Discuss
Answer: (a).Trellis code modulation Explanation:Forward error correction is carried out to reduce the number of bits received in error. It can be integrated into demodulation process such as in Trellis code modulation. It can be closely associated with demodulation process such as in soft decoding of convolution codes.
Q64.
Which of the following is not included under MAC processing?

a.

Framing

b.

Frame synchronization

c.

Error detection

d.

IP addressing

Discuss
Answer: (d).IP addressing Explanation:Media Access Control processing includes framing information, frame synchronization, error detection, MAC addressing, link management, and payload encapsulation. The output of this stage is in the form of bits.
Q65.
Network processing layer is designed with ____ connectivity support.

a.

point-to-point

b.

hop-to-hop

c.

end-to-end

d.

hop-to-point

Discuss
Answer: (c).end-to-end Explanation:The network processing layer is preceded by medium access control. The input to network processing layer is in the form of bits. The network processing layer is designed with end-to-end connectivity support and its output is transferred to the application layer.
Q66.
The external RF components must be provided with ____ for effective control of parameters such as tuning frequency.

a.

control unit

b.

physical wires

c.

digital interfaces

d.

transceiver

Discuss
Answer: (c).digital interfaces Explanation:The external RF components must be provided with digital interfaces for effective control of tuning frequency, transmit/receive mode, VSWR, transmit power level sensing and gain control.
Q67.
Which among the following is not considered for detection of abnormal behaviour in power amplifier?

a.

Temperature

b.

Transmitted power level

c.

Received power level

d.

VSWR

Discuss
Answer: (c).Received power level Explanation:Power amplifier is a part of RF front end section in transmit mode. It must be informed of transmit/receive mode to start and stop transmission. Transmitted power level, VSWR, and temperature are monitored for detection of abnormal behavour in power amplifier.
Q68.
Web browsing requires ____ for effective operation.

a.

low latency

b.

data cache

c.

buffer

d.

fast computation

Discuss
Answer: (b).data cache Explanation:Web browsing needs to store information of webpages which are frequently accessed to avoid transmission of redundant information. Large data cache is required to store the specified information. It is typically implemented using local hard disk.
Q69.
Ad hoc network introduces jitter in packet delivery.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:In ad-hoc networking, the reception and re-transmission of signal at each node introduces an overall non-uniform delay. Thus ad hoc network introduces jitter in packet delivery and is compensated by using jitter buffer.
Q70.
Each time the transceiver changes frequency, the antenna tuner will need to be informed of the new frequency.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Each time the transceiver changes frequency, the antenna tuner will need to be informed of the new frequency. The antenna tunermay sense VSWR and adjust the tuning elements to minimize VSWR.
