ASIC

Discuss
Answer: (a).DSP Explanation:The application processer usually runs voice coder, video coder, data coder, and web browser functions. Speech and video applications run on DSP processor. Text and web browsing run on GPP processor.
Q52.
Which of the following is not a characteristic of cryptographic security?

a.

Confidentiality

b.

Authentication

c.

Authorization

d.

Latency

Discuss
Answer: (d).Latency Explanation:The cryptographic security function must encrypt any information to be transmitted. Confidentiality, data integrity, authentication, source authentication, authorization and non-repudiation are the characteristics of cryptographic security as defined by US National Institute of Science and Technology (NIST).
Q53.
____ is used to identify the creator of information.

a.

Integrity authentication

b.

Source authentication

c.

Integrity authorization

d.

Source authorization

Discuss
Answer: (b).Source authentication Explanation:Integrity authentication verifies the reliability of data. Source authentication is used to identify the creator of information. Digital signature and key agreement techniques are examples of authentication services.
Q54.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Each application has a distinctive encryption process, and encryption cannot be generalized. The Digital Encryption Standard (DES) and Advanced Encryption Standard (AES) from US National Institute of Technology (NIST) monitor the standard for cryptographic process.
Q55.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Antenna matching unit is a part of RF front end section in transmit mode and in receive mode. In transmit mode, the modem controls the antenna matching unit to minimize voltage standing wave ratio.

a.

Antenna-matching unit

b.

Radiating element

c.

Antenna tuner

d.

Power amplifier

Discuss
Answer: (c).Antenna tuner Explanation:Antennas, operating over a wide frequency range, use antenna tuner to optimize the voltage standing wave ratio. It also results in improvement of radiation efficiency.
Q57.

a.

multiple input multiple output

b.

single input single output

c.

single input multiple output

d.

multiple input single output

Discuss

a.

only transmission

b.

only reception

c.

transmission and reception but not at the same time

d.

transmission and reception

Discuss
Answer: (d).transmission and reception Explanation:Full duplex means transmission and reception will be carried out simultaneously. Filtering may be done to prevent interference between high power transmission signal and low power received signal.
Q59.
____ filters can be used to aid full duplex communication.

a.

Surface wave acoustic

b.

Surface acoustic wave

c.

Skin wave acoustic

d.

Skin acoustic wave

Discuss
Answer: (b).Surface acoustic wave Explanation:Full duplex means transmission and reception will be carried out simultaneously. Bulk acoustic wave filters, Surface acoustic wave filters, Yttrium-Iron-Garnet circulators are complex structures used to aid full duplex communication.
