Connexions - share educational material

A place to view and share educational material made of small knowledge chunks called modules that can be organized as courses, books, reports, etc. Anyone may view or contribute.

Connexions - share educational material

Connexions is a dynamic digital educational ecosystem consisting of an educational content repository and a content management system optimized for the delivery of educational content.

A First Course in Electrical and Computer Engineering

Provides readers with a comprehensive, introductory look at the world of electrical engineering. It was originally written by Louis Scharf and Richard Behrens at the University of Colorado. This collection includes MATLAB exercises and diagrams that step readers through a broad range of topics, including phasors, circuit analysis, binary coding, and more.

Freshman Engineering Problem Solving with MATLAB

This course, originating at Arizona State University at the Polytechnic Campus, is intended to introduce freshman engineering students to problem solving using an m-file environment, such as MATLAB, LabVIEW MathScript, Octave, etc. It is designed for the novice programmer, and covers the most commonly used features of the language.

 Digital Electronics Education


Digital Electronics Education

The objective of Advanced Digital Electronics courses is to bridge basic logic gates (combinational circuits) with technical topics related to binary counter topologies (Asynchronous & Synchronous), shift registers, memory, and DSP (Digital Signal Processors) which fall under the sequential devices umbrella

Principles of Semiconductor Devices

The purpose of this text is to explore the internal behavior of semiconductor devices, so that we can understand the relation between the device geometry and material parameters on one hand and the resulting electrical characteristics on the other hand.

Principles of Semiconductor Devices

Principles of Semiconductor Devices

"The Primary Focus: The MOSFET and CMOS Integrated Circuits The Metal-Oxide-Silicon Field-Effect-Transistor (MOSFET) is the main subject of this text, since it is already the prevailing device in microprocessors and memory circuits. In addition, the MOSFET is increasingly used in areas as diverse as mainframe computers and power electronics. The MOSFET’s advantages over other types of devices are its mature fabrication technology, its successful scaling characteristics and the combination of complementary MOSFETs yielding CMOS circuits."

Some of the Topics
  • Schottky diode current
  • Metal-Semiconductor contacts
  • Electrostatic analysis of a p-n diode
  • Reverse bias breakdown
  • Optoelectronic devices
  • Light Emitting Diodes (LEDs)
  • Ideal transistor model
  • MOSFET SPICE MODEL
  • Power MOSFETs

Technical Resource - Marc Dekenah

Useful resource on Power Quality, Radio Telemetry, T&M and Interfacing.  Marc's Technical Pages; knowledge-base of Faultlink International, an independent electrical / electronics fault investigation & analysis consultancy.

Technical Resource - Marc Dekenah

Economical Impulse Generator, Measuring in Excess of 1kV, "Soft Earthing" Instruments and A Real LAN twist cable are pages you must read.

Technical Resource - Marc Dekenah

Marc is an independent electrical/electronic fault investigation and analysis consultant with over 25 years of industrial electrics/electronics experience as Consultant, System Engineer, Technical Director, Design Engineer and more.

Connecting Up For Intermittent/Nuisance Trips

"Intermittent trips are circuit breakers rightfully operating because of an unknown cause or fault. Nuisance trips are a breaker deeming a non-existent fault has occurred and, in so doing, operates without need."

FaultLink International - Electrical Power Diagnostics

"Faultlink International is a fully independent broad-range electrical/electronics fault investigation and analysis consultancy."

Product Design Precautions

When you design a new Product or Engineer an existing one; communications and documentation is important. Creating a satisfying solution is the main thing. If requirements and specs or not properly developed it can lead to blame-games, wasted time and spoils the reputation.

A firm also should do proper market study before the decision to design a product. Even a well designed product cannot be sold if it does not offer a cost-effective solution.

Product Design Precautions
  • Start Projekt {
  • Customer Interaction and Communication to make a specs sheet and drawing.
  • Block Diagram, feasibility, cost, risk, samples demo and study similar ideas.
  • Effective designs are cost effective within customer budget, draft BOM costing.
  • Circuit and Code design and get more inputs from customer and then freeze specs.
  • Build Dummy for ergonomics and discuss, Prototype and start test at site or simulate.
  • Calibration and testing and production documentation drafts final costs.
  • Pilot Production of a small batch, rigorous test batch, and freeze production documents.
  • Documents and Prototypes to be given to Production Engineering.
  • Production Engineering continue engineering maintenance and quality issues.
  • } End Projekt
