Re: Transformer history
Of course, these transformers are rather more sophisticated that the ones that George Westinghouse and Charles Steinmetz were working with. Somewhat wider bandwidth and more predictable response with regard to common- and differential-mode behavior.

Re: Transformer history
Sorry,I forgot to include the link to an interesting resource on their history:

http://edisontechcenter.org/Transformers.html

and there are many more you can find.

Transformer history
Interesting that the transformer--among the oldest electrical components--still finds so may roles. The induction principle was discovered in the 1830s, and the first commnercial transformers were used in the 1880s--but they were for power, not signal.

A properly designed and used transformer can be an extremely reliable device and a solution to a lot of problems in signal isolation, baluns (as this blog shows), power transfer, voltage/current step-up/down, impedance matching, and many others. Not bad for a "dumb", passive part!

As an engineer, eventually you will have to insert an equation into your written work or presentation. This can be a struggle as equation editors are not always the friendliest. However, there is good news. The equation editor in Word has improved immensely (I am using version 2010 here). In this blog we look at how to insert an equation into a Word document. As a bonus, there is information on how to insert an equation into a web page with an html code generator website.
Wait a minute. Let’s see if I understand this. (Here I’m channeling you, the puzzled reader, after you’ve grabbed me in the coffee break of a Filter Wizard lecture morning). The frequency of the nth harmonic of a sinusoid is n times that of the fundamental. The nth harmonic distortion is defined as the ratio of the amplitude of the nth harmonic to the amplitude of the fundamental. So the 1st harmonic distortion is… the ratio of the amplitude of the fundamental to the amplitude of the fundamental and that’s… unity. I. Do. Not. Understand.
Single-ended signals are very common, but increasingly signal paths are being converted to differential signals as part of the signal chain. The benefits of differential signaling are particularly appealing with low supply voltage systems and for driving analog-to-digital converters (ADCs).
If you spend any time at all looking at alternative energy sources such as wind power and solar energy, you'll quickly discover one inconvenient truth: alternative energy production is both highly unpredictable and uncorrelated to energy demand.
When Radio Shack announced that they were closing stores, unfortunately the one in Cupertino (De Anza Blvd.) was one of them.
