This book guides engineers through the use of the Costas loop, which can be considered an extension of the better known Phase-locked loop. The author discusses all three variants of the Costas loop and describes their dynamic behavior, using newly developed mathematical models. Step-by-step design procedures and Simulink models are included for every type of Costas loop.  These models enable designers to test circuits prior to building breadboards or prototypes, accelerating the design process considerably.

Roland Best (Zurich, Switzerland) is the founder of Best Engineering and world-renowned authority of phase locked loops, circuit design, and microprocessor applications. Dr. Best has worked for Sandoz A.G. and the IBM Research Laboratory in Zurich.
