Introduction
Welcome to Circuit Exchange International. My site contains electronic and radio schematics, simulation and
circuit design. In addition I have created a practical section including tutorials. This is a free site and
mostly my work, however I do welcome contributions. Everyone who has helped in the making of this site is listed
on my
credits page. This home page has kindly been translated into several languages,
and you can use google translator for others. Thank you for visiting my site.
