AN UP-DOWN COUNTER FOR USE WITH SHOCK-TUBE INSTRUMENTATION,

Abstract

An up-down counter was designed and built to provide precise synchronization of instrumentation used with the HDL pressure-driven shock tube. The counter is intended to trigger instruments measuring phenomena associated with the arrival of a shock wave. The counter described demonstrated proper operation over a range of 75 to 145 microseconds, repeatable to less than plus or minus 1 microsecond. The report includes a detailed description of the design and techniques employed in this application. (Author)
