The Published Articles of John Linsley Hood

 

 

Following the sad news regarding the death of Mr J L Linsley HoodMIEE on 11/3/2004, I thought that a comprehensive index of his published works would be a fitting addition to this website. I have therefore compiled the following list from my own archive of magazine articles, an on-line index of more recent Electronics World articles, web searches and input from various helpful people around the world.

 

A link for those who prefer their lists to be sorted by category.
