Q91.
____ is obtained by the product of number of parallel hardware elements and clock speed.

a.

MIPS

b.

MOPS

c.

MFLOPS

d.

KPI

Discuss
Answer: (b).MOPS Explanation:Millions of operation per second (MOPS) is obtained by the product of number of parallel hardware elements and clock speed. An operation (OP) is a logical transformation of data carried out by portion of hardware in one clock cycle.
Q92.
A combination of a band and mode is called ______

a.

matched pair

b.

matched set

c.

type

d.

personality

Discuss
Answer: (d).personality Explanation:Each combination of band and mode is a multiple personality. A personality combines RF band, channel set, air interface waveform, protocol, and related functions.
Q93.
Which of the following is not a hardware module?

a.

Memory

b.

DSP

c.

Workstation

d.

RF

Discuss
Answer: (d).RF Explanation:The development of a SDR involves accurate analysis of functional and statistical structure of hardware and software. The key step in system analysis is the identification of processing resources and characterization of processing capacity of digital hardware. Memory, DSP and workstation are few examples of digital hardware.
Q94.
____ is a technique where multiple instructions are overlapped during execution.

a.

Pipelining

b.

Caching

c.

Instruction fetching

d.

Mapping

Discuss
Answer: (a).Pipelining Explanation:Pipelining is a technique where multiple instructions are overlapped during execution. Pipeline consists of many stages that vary from processor to processor. Pipelining increases the overall throughput of instruction execution.
Q95.
____ serves as a system control processor.

a.

ADC

b.

Bus host

c.

DSP

d.

Memory

Discuss
Answer: (b).Bus host Explanation:Bus host serves as a system control processor. Analog to Digital Converter is responsible for the conversion of an analog signal into a digital signal suitable for further processing. Digital Signal Processor supports real time channel processing.
Q96.
Which of the following is not a type of digital-interconnect?

a.

DSP

b.

Dedicated interconnect

c.

Wideband bus

d.

Shared memory

Discuss
Answer: (a).DSP Explanation:Dedicated interconnect, wideband bus and shared memory are different types of available digital-interconnect. In dedicated interconnect, the vendor of a board provides a suitable interconnect. Shared memory reserves a block of memory for communication. The performance of shared memory can be enhanced by operating with programmable Direct Memory Access (DMA) or equivalent hardware.
Q97.
Interconnect efficiency is a function of ____ being transferred.

a.

number of data blocks

b.

size of data blocks

c.

type of data blocks

d.

accuracy of data blocks

Discuss
Answer: (b).size of data blocks Explanation:Interconnect efficiency is a function of size of data blocks being transferred. Most buses exhibit low throughput for smaller block size. In addition to block size, features such as Direct Memory Access overhead, handshaking mechanism affect the overall throughput.
Q98.
MFLOPS stands for Millions of Fixed Point Operation per Second.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:MFLOPS stands for Millions of Floating Point Operation per Second. An operation (OP) is a logical transformation of data carried out by portion of hardware in one clock cycle. MIPS, MOPS, MFLOPS are differentiated by their logical scope.
Q99.
Architecture of local and global memory among processors can contribute to algorithm performance.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Architecture of local and global memory among processors can contribute to algorithm performance. Balancing high speed data flow and bandwidth reduction leads to clustering of memory and processing capacity.
Q100.
Which of the following is the first step in FEC decoding?

a.

Input bitstream synchronization

b.

Descramble

c.

Decode

d.

Symbol puncturing

Discuss
Answer: (a).Input bitstream synchronization Explanation:The first step in FEC decoding is input bitstream synchronization. It is followed by reversing the effect of symbol puncturing and estimation of transmitted bits. Then the resulting signal is decoded and descrambled.
