Introduction to PCM Telemetering Systems, Third Edition summarizes the techniques and terminology used in sending data and control information between users and the instruments that collect and process the data. Fully revised, it gives an overall systems introduction to the relevant topics in three primary areas: system interfaces; data transport, timing, and synchronization; and data transmission techniques. Integrating relevant information about the process at all levels from the user interface down to the transmission channel, this will also include how designers apply relevant industry and government standards at each level in this process. Homework problems are included at the end of each chapter.
"Dr. Horan has taken the best end-to-end textbook on telemetry systems and updated it to include important emerging issues in the field. For example, in the area of smart sensors, Dr. Horan has added coverage of RFID while in the area of computer systems elements, he has added a section on secure communications."

"…a very good reference book for those who work in the aerospace and space flight arenas, especially for those who are not well versed in the telecommunication field. If nothing else, learning about the jargons and basic building blocks in telemetering systems, and seeing real life examples will help lower the anxiety level when dealing with the field as a part of a person’s job."
