Abstract
A system for accumulating and processing data derived from plural transducers, such as an array of shaft position-measuring resolvers and/or other monitored parameters, includes multiplexing apparatus for converging the outputs of the transducers and the like upon sample-and-hold circuits and an analog-to-digital converter. The digitized signals are operated on by a reference signal in a synchronous demodulator, smoothed in a recursive digital filter operative in conjunction with the stored contents of a read/write memory (RAM), and stored in prescribed memory cells.
