Sensing process mainly consists of ____

a.

actuators and networks

b.

sensors and data-processing methods

c.

sensors and actuators

d.

actuators and data-processing methods

Discuss
Answer: (b).sensors and data-processing methods Explanation:Similar to the location and environment awareness features appearing in nature, location and environment awareness engines consist of three stages namely sensing, awareness, and adaption. Sensing is the first step and is accomplished by sensors and data processing methods.
Q3.
____are used to convert acquired signals from the environment into ____ signals suitable for cognitive radio.

a.

Sensors, physical

b.

Sensors, electrical

c.

Actuators, electrical

d.

Actuators, physical

Discuss
Answer: (b).Sensors, electrical Explanation:Sensors are used to convert acquired signals from the environment intoelectrical signals suitable for cognitive radio. It is critical to learn and interact with the environment. The acquired signals may be electromagnetic, optic or sound.
Q4.
Radio sensing is a technique that utilizes ____

a.

hearing sensors

b.

electromagnetic sensors

c.

image sensors

d.

acoustic sensors

Discuss
Answer: (b).electromagnetic sensors Explanation:Radio sensing is a sensing technique that utilizes electromagnetic sensors. Radio vision is a sensing technique that employs image sensors. Radio hearing is a sensing technique that utilizes acoustic sensors.
Q5.
Which among the following is not an example for electromagnetic sensors?

a.

Antenna

b.

CCD sensors

c.

RF sensors

d.

Anisotropic magneto resistance sensors

Discuss
Answer: (b).CCD sensors Explanation:Electromagnetic sensors are used to convert electromagnetic signals into electrical signals. Antenna is the most commonly used radio sensing sensor. Location information is obtained from received signal statistics such as time of arrival in antenna based wireless positioning system.
Q6.
Which among the following is type of image sensor described by its structure?

a.

Colour

b.

Monochromatic

c.

Global

d.

Charge Coupled Device

Discuss
Answer: (d).Charge Coupled Device Explanation:An image sensor detects light waves and converts into signals of small bursts of current that convey information to form an image. The image sensors are classified as Complementary Metal Oxide Semiconductor or Charge Coupled Device based on structure and colour or monochromatic based on chroma type.
Q7.
Image sensors contain ____ made of light sensitive elements.

a.

film

b.

frames

c.

photons

d.

pixels

Discuss
Answer: (d).pixels Explanation:Image sensors contain pixels made of light sensitive elements, micro lenses, and micro electrical components. The sensor also has wire bonds, cover glass, contact pads and interconnecting paths.
Q8.
The function of cover glass is to ____

a.

prevent entry of light

b.

protect the sensor

c.

transfer signals

d.

protect contact pads

Discuss
Answer: (b).protect the sensor Explanation:The cover glass is the top most layer providing protection to the sensor and wires while allowing light to reach light sensitive area. The wires transfer signals to the contact pads which is the bottom layer. The package is used to protect contact pads.
Q9.
Which among the following is not an action carried out in image formation?

a.

Analog to digital conversion

b.

Digital to analog conversion

c.

Conversion of photon into electron

d.

Conversion of signal charge to electrical signal

Discuss
Answer: (b).Digital to analog conversion Explanation:The first step in image formation is the conversion of photons into electrons. The charges are then collected and transferred. The charge is then converted into an electrical signal such as voltage which is then converted into a digital signal using an analog to digital converter.
Q10.
____ can convert a scene into text or voice.

a.

Cognitive sensing system

b.

Adaptive sensing system

c.

Cognitive vision system

d.

Adaptive vision system

Discuss
Answer: (c).Cognitive vision system Explanation:Computer vision aims to provide human like vision and perception to computers. Cognitive radios with cognitive vision systems can covert a scene into a text, voice or an image based on the application. These systems are limited by size and cost.
