3. Portable Audio Equalizer
Objectives
The system should have excellent sound quality.
The system should have easy equalization
The system should be lightweight
The system should be low cost
Constraints
The system must be portable
The system will be an add-on to an existing MP3 player

4. Concept Fan
The Concept Fan is a way of discovering alternative approaches to a problem when you have discarded all obvious solutions. It develops the principle of 'taking a step back' to get a broader viewpoint. Initially, the Concept Fan requires you to draw a circle in the middle of a large piece of paper. Write the problem you are trying to solve in the circle. To the right of it radiate lines representing possible solutions to the problem (concepts), see the diagram below:

5. Concept Fan
It is possible that the ideas you have come up with are impractical or do not solve the problem. If this is the case, take a 'step back' for a broader analysis of the problem. Drawing a circle to the left of the first circle does this, writing the broader definition into this new circle and linking it with an arrow to show that it comes from the first circle, see diagram below:
Use this as a starting point to radiate out other ideas; if this does not give you an adequate amount of new concepts, you can take yet another step back (and another, and another…)

7. Concept Combination Table
A Concept Combination Table (also called morphology box) is a matrix of concept fragments organized by functions (each function forms a separate column) so that an integrated concept can be created by choosing any concept fragment for each function and combining them to complete the required functionality.

13. End Product Description
In this section you will describe:
The constituent modules and their interrelationships
The functionality of the product
The functionality of the different modules
Present the product specs

14. Black Box
In science, computing, and engineering, a black box is a device, system or object which can be viewed in terms of its inputs and outputs (or transfer characteristics), without any knowledge of its internal workings. Its implementation is "opaque" (black). Almost anything might be referred to as a black box: a transistor, an algorithm, or the human brain.

15. Block Diagram
A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams.

16. End Product Description
To obtain the block diagram of a design we use a method based on levels
We start with Level 0, which is the black box description of the project.
We uncover Level 0 and see the Level 1 modules
We continue this process until the step before placing components
At each step we provide the modules' functions and interconnection specifications

17. Level 0 Equalizer Functionality
This is the product description without knowledge of the internal blocks (black box)

18. Level 1 Equalizer Functionality
This a general Description of the internal blocks
Only Pre-AMP table shown.
Show a table for each block

19. Level 2 Automatic Level control (ALC)

20. Embedded Systems Require additional Information
Pseudo Code or Flow Charts are required

21. Continue until the next step is to place components

22. Conventions
Use buses (Thick lines) to represent several connecting lines that have common origin and destination
Terminate the bus with an arrow head at the destination
When information flow is bidirectional, place arrows at both ends of the bus
When possible indicate the number of lines

23. Conventions At some level of detail all individual lines must show
Images from:
and
Remember, stop when the next step is placing components

24. In Summary
Describe diagrams in paragraphs with local functionality tables slides (11 to 14)
Repeat Functionality Tables
Put level 0 functionality in one table
Group all level 1 functionality tables in one table
Repeat for all levels
At the end of de section include the Technical Specs that you obtained before
