Thank you for visiting Electronics Notes. On the site I aim to provide accessible summaries, and information with a minimum of jargon covering many electronics engineering topics. All the topics are manually written by myself and the aim is to provide useful information that is easy to understand and to include many hints, tips & practical guidance notes using my experience from my many years as an electronics engineer.
Electronics Notes is written and run by Ian Poole
Carbon Composition Resistor
The carbon composition resistor was widely used for many years, but since the 1960s it has been superseded by other types with better performance although it is used in some specialised applications.
Doherty Amplifier Concept
The Doherty amplifier is a form of power amplifier that provides increased efficiency levels when used with signals that have a high peak to average power ratio. Find out more . .

Electronics Notes aims to provide accessible summaries about a host of electronics, radio and connectivity technologies in a practical and useful way.
Our aim is to support those who want to learn about the technology: those who are established engineers as well as students and hobbyists.
The topics included in the site range from the basic electronics concepts (useful for established engineers as well looking for those equations, formulas etc, including topics like basic electronics concepts, component descriptions and explanations, circuit designs and circuit design principals, manufacturing techniques, radio technology & RF design and wired and wireless connectivity and a host of other topics.
To fund the running of the site, we obviously need to carry advertising, but we aim to make this not too intrusive. We hope you understand, but we need to have income to meet the not inconsiderable running costs.
