EE 460 Quiz 5

This category of functional elements is subject to the Shannon-Hartley theorem

Information Elements

This category of functional elements is subject to the Nyquist Noise theorem :

Signal Elements

Each functional element identified during partial function decomposition has only one embodiment.(True/False)

False

A system functional element identified during partial function decomposition implements as a Commercial-off-the-Shelf (COTS) component. The functional element exhibits this property.

Commonality

The commonality of a system functional element is an important consideration when the cost is a CTQ driver.(True/False)

True

One needs a complete set of THESE engineering specifications to adequately describe a functional element. (mark all that apply)

Functional, Interface

The enclosure is NOT a functional element. (True/False)

False

Torque and thrust are words most often associated with this functional category:

Energy Elements

Display is a function (verb) most likely associated with this functional category:

Data Elements

These categories of functional elements are subject to conservation laws (mark all that apply)

Energy Element, Material Elements

In a functional decomposition, one needs to capture the Dominant Flow ONLY. (True/False)

False

If a functional element is significant, singular, and common its embodiment also has the same properties.

True

Which of the following network architectures exhibit an almost linear relation between the number of elements and the number of connections (mark all that apply)

Line, Full mesh, ring

A system consists of 8 functional elements and 30 element-to-element connections. The functional elements have high cohesion.(True/False)

False

Conversion is a common system function. This converter type is subject to quantization noise.

Analog-to-digital converter

Priority encoding has the following dominant flow:

Data

Cyclic Redundancy Check (CRC) has the following dominant flow:

Data

Level-zero (L-0) decomposition of a system typically comprises that many functional elements

1

Level-1 (L-1) decomposition of a system typically comprises that many functional elements:

fewer than 10

Students argue they do not need to perform functional decomposition b/c their project involves writing software for image processing. How should the EE460 instructor respond; select the two best responses.

1) Interesting. Are you familiar with the term "pseudocode"? Have you used a flowchart to represent an algorithm before?
2)Your system has a dominant data flow. The overall system function seems complex; to flash out the algorithm, functional decomposition is appropriate.

When dealing with signals, one must think of power and energy b/c most signals are conjugate variables of energy. (True/False)

True
