This course, of 30 lectures, is given to Physics undergraduates in the
3rd and 4th years. Its objective is to provide a systematic introduction
to the world of electronics to physicists. The emphasis is on the basic
concepts of analogue electronics. The analysis and understanding of simple
circuits is based on a black box, functional approach, with extensive use
of simplified equivalent circuits.
