Circuit Analysis

[Aentons]

In addition to the Tutorials section, I think it would be helpful to have a collection of links to all the different detailed circuit analysis pages scattered around the internet. These are Not "How To's" like tutorials, but are detailed descriptions and explanations of well know circuits, not generalized concepts. Please post a link to any that I've missed.


Let's kick it off with none other than R.G. Keen's...

I would also recommend Kit Rae's amazingly useful Big Muff site:

Storm Tide Flanger
http://jhaible.com/legacy/jh_storm_tide_flanger.html

This is a clone of the Eventide Instant Flanger, the greatest analog solid-state flanger ever made. To get the PDF's to download on the links at the bottom, you have to right-click and choose "Save Link Target As...". Just clicking those links opens a blank page.

Here's a link to a PCB for newest version of this project. Just looking at the PCB, this would be by far the best/most complicated analog flanger you could ever build. Not bad for $74.
