Stresses how A/D and D/A converters operate, their important parameters and how to choose the best type for an application. Contains pertinent information on analog switches and comparators; reference voltages; how to power, ground and shield analog circuitry used in conversion systems to obtain desired accuracy and dynamic range. Features one of the few operational descriptions of code wheels used to perform rotational-to-digital conversion. Organized to allow readers to go directly to the subject conversion data of interest.
