Sinossi
Part of a series this book deals with the principles of phase-sensitive detection and with the specification and handling characteristics of modern lock-in amplifiers. Among the topics included are applications for two-phase lock-in amplifiers, the problems of phase-locking to very noisy signals, a review of system configurations for heterodyne and PWM lock-in amplifiers and the use of lock-in amplifiers in computer-controlled measurements. The material is presented at systems level throughout and covers many practical aspects of signal recovery in research applications.
