Design of intertransition digitizing decomutator. Final report

Development of automated test equipment for an advanced telemetry system in weapon applications requires capturing and analyzing Terminal Data Analyzer (TDA) data. TDA data is generally a quick burst of Pulse Code Modulated (PCM) data which relates the status of the weapon just prior to impact. Many systems use bit sampling to capture the state of the data stream at periodic intervals. This method may fail to capture glitches in the data stream if two transitions occur between sampling intervals. A more complete method of data capture was desired. The solution was intertransition digitization. Intertransition digitization captures all transitions in the data stream while keeping track of the time elapsed between transitions
