A deep ocean capsule is proposed capable of sensing
pressure, temperature, flow and direction for a study of
tides and internal waves of the oceans. One of the major
requirements for this capsule is the detection and recording
of unusual events. To meet this need a very low power,
highly reliable digital detector has been designed. COS/MOS
logic with maximum use of MSI and LSI was used in the design.
The detector was simulated using proposed word
lengths and fixed point arithmetic which would be utilized
in the ensuing hardware. The fixed point simulation was
necessary to verify the problems in truncation and round-off
errors and to provide necessary design criteria to ensure
proper filter functioning and integral detection.
