I have been writing articles for magazines since the early 1970s, and many of these have been published in Electronics World (founded in 1911 as The Marconigraph but known for most of its life as Wireless World). This is undoubtedly the foremost electronics magazine in the UK, being widely read by professional electronics engineers on the one hand, and the more advanced electronics enthusiasts and hobbyists on the other, both in the UK and throughout many countries of the world, English-speaking and otherwise. A collection of these articles was published in 1995, under the title Analog Circuits Cookbook. This proved very popular, and the present companion volume is the result of a suggestion that further articles of mine from Electronics World should likewise be republished. Most but not all in this present collection of articles were published since the preparation of the earlier volume. And all appeared under the name Ian Hickman except two, which originally appeared under other pen names.

Inevitably, in the preparation for publication of a magazine which appears every month, the occasional 'typo' crept into the articles as published, whilst the need to adjust articles to fit the space available led to the occasional pruning of text. As in the previous volume, the opportunity has been taken to restore the excised material, whilst it is hoped that most if not all errors in the articles as published have been identified and corrected. Each article has been prefaced with a brief introduction, indicating the contents and its general drift.
