This book is different to other electronics texts available. First, it is short. Created for a one-semester course taken by physics students, both undergraduate and graduate it includes only the essentials and covers those topics only as deeply as needed in order to understand the material in the integrated laboratory exercises. Unlike many electronics texts for physics students, this one does not delve into the physics of devices. Instead, these are largely treated as black boxes having certain properties that are important to know for designing circuits. The physics comes when the students use their acquired electronics instrumentation knowledge to construct apparatus to make measurements. Since the detailed physics has been left out, this book should be equally useful for students in any of the physical or life sciences. This is the first textbook aimed at the non-electrical engineering student, that has both the generality on analog and digital electronics circuits, coupled to the very timely technology of embedded electronics. The book also features homework exercises, parts list and a suite of useful appendices.
