Basic Design Sequence

Structured design uses a design method that is equal at each hierarchical level of the product design.

Presentation

The presentation “Basic Design Sequence” shows the basic sequence of activities that converts a initial requirement for a physical object, at any hierarchical level, into a physical breakdown of sub-assemblies or parts.

Information Processing: Definitions

In structured electronics design, we consider electronic products as information processing systems.

Presentation

The presentation “Information processing: definitions ” gives the definitions of some basic terms used in information processing.

Shannon: Channel Capacity

The expression for the channel capacity (Shannon 1948) shows us that there are three fundamental limits to the amount of information that can be processed by any real-world system:

• noise addition

• power limitation

• speed limitation

Presentation

The presentation “Shannon: Channel Capacity” briefly elucidates this.

Outline of Structured Electronic Design

1. Although not scientifically proven, we assume that the functional breakdown of information processing systems can be made with a limited number of basic electronic processing and reference functions.

2. By taking a limited number of functions as starting point for a design, rather than an almost infinite number of known circuits, is one of the keys of structured electronic design.

3. Functions concepts describe the idealized desired behavior of their real world implementations. The information handling capacity of these objects, however, is limited. This is a result of:

   1. Noise addition

   2. The physical limitation of the signal power

   3. The physical limitation of the rate of change of a signal

   4. Imperfect technological implementation of the desired functional behavior (physical operation mechanism)

4. The performance-to-cost ratio of an implementation can be improved through application of a limited number of error reduction techniques.

5. Orthogonalization of the design process can be obtained by proper sequencing of the design of different performance aspects.

Amplifiers: performance measures, cost factors and figure of merit

During the design it is important to have some figure of merit for design solutions. Comparison of the figure of merit of different solutions is the basis for taking properly motivated design decisions.

Presentation

The presentation “Amplifers, performance measures and cost factors” gives a general performance measures and costs factors for amplifiers en proposes a figure of merit that can be used throughout the design process.
