Abstract

Digital telemetry filter is an essential subsystem of ground instrumentation which is a part of flight test instrumentation used for military aircraft flight testing. Flight test instrumentation includes on-board instrumentation and ground instrumentation. Typical waveform used in telemetry system for flight testing, which is hybrid in nature (PCM+FM+FM/FM), is multiplexed in frequency domain. Digital telemetry filter plays a critical role to separate data (PCM), hot mike (FM) and vibration (FM/FM) from the received baseband signal during flight test in real time. This paper describes a pipelined approach for the implementation of high speed digital telemetry filter for flight test on low power field programmable gate arrays (FPGA). This paper also provides a brief discourse on the effective application of VLSI design methodologies for efficient implementation of digital filter algorithms. The filter is designed in VHDL, simulated using ModelSim, synthesized using Quartus-II and the implemented on Cyclone-II FPGA.
