This up-to-date volume provides an essential part of undergraduate physics training. Until now, students were often expected to learn many experimental methods in the laboratory without proper introduction. The broad coverage of available techniques includes discussion of state-of-the-art electronic equipment, as well as such topics as discrete semi-conductor devices, signal instrumentation, and X-ray diffraction methods. Professor Dunlap's text will serve not only as a complete introduction for students but also as a reference work for technicians throughout a professional career. In addition to tutorial discussion presented, tables of numerical data and constants are included, further enhancing the book as a permanent reference.
