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.

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
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.
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.
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:
Noise addition
The physical limitation of the signal power
The physical limitation of the rate of change of a signal
Imperfect technological implementation of the desired functional behavior (physical operation mechanism)
The performance-to-cost ratio of an implementation can be improved through application of a limited number of error reduction techniques.
Orthogonalization of the design process can be obtained by proper sequencing of the design of different performance aspects.

The presentation “Outline of Structured Electronic design” briefly elucidates the above.

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.

Amplifiers: basic function design approach
The design approach for basic functions is based upon the:
Definition of the function concept
Discovery of an operating mechanism and associated design parameters
Application of error reduction techniques for improvement of the performance-to-cost ratio
Presentation
