This paper provides a brief historical discussion of the development of time division low level multiplexing techniques and especially emphasizes MOS-FET multiplexers currently being implemented. Error sources which may affect system accuracy and therefore must be considered in the design of the multiplexer are described. Some of the more significant of these errors: aliasing, interchannel crosstalk, static offset, transient coupled errors, and common-mode injected errors are analyzed and covered in detail. Equations expressing the overall interchannel DC crosstalk and static offset for a generalized multiplexer are derived and presented. Settling errors arising from transient events in time division multiplexers are derived for a two channel multiplexer and plotted to illustrate their dependency on the multiplexer input and output capacitances. A multi-tier channel path is also examined for common-mode to differential-mode signal conversion. As a conclusion, the author discusses how these error sources accumulate and gives a means for predicting the overall cumulative average error to be expected from the time division multiplexing equipment.

A 64 to 1 monolithic multiplexer for video signal switching applications was designed. The performance analysis and the testing of the first devices fabricated and packaged show close agreement in on channel resistance and on channel bandwidth. Other requirements, such as off channel isolation and output signal distortion, have poorer agreement in the calculated values versus the measured data. Arguments for these differences are presented.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Subcarrier use in telemetry has decreased in recent years due to emphasis on all-digital systems, but some cases lend themselves more easily to a mixed-service system carrying subcarriers along with a baseband signal. The 'IRIG 106' Telemetry Standards have maintained and expanded several series of FM subcarriers, but some uses are better served with 'non-standard' subcarriers that might be standard in other types of service, making components relatively easily available and inexpensive. This paper examines topics from the RCC study and describes some of the uses of subcarrier systems available to the telemetry designer.
