Digital FDM for the HSTSS DAC Program

摘要

This paper presents the design of an innovative approach to Frequency Division Multiplexing (FDM) for the STRICOM Hardened Subminiature Telemetry and Sensor System (HSTSS) Data Acquisition Chipset (DAC) program. An ASIC (Application Specific Integrated Circuit) is being developed by Systems & Processes Engineerign Corporation (SPEC) that implements this new digital FDM approach for telemetry applications. The FDM ASIC provides six channels that are IRIG-106 compatible, and may be used in conjunction with a Delay/Repeater ASIC. Together these ASICs make a complete instrumentation system for those applications requiring very small size, simplicity of use, and low cost, e.g. munitions/armament testing.
