Description -
In recent years great advances have been made in the use of electronic devices in industries outside the sphere of ‘communications’. Mr. Henney's book should do much to further the advance. The author, who deals with the varied and sometimes little appreciated applications of electron tubes, is closely connected with many sides of the world of electronics, and this book should find a place on the shelf of every industrial engineer.
