An analysis of Clock Sounds

Abstract

The detection of a clock or clock-type mechanism in a piece of ordnance is a problem for the EOD man. This report describes an exploratory investigation to determine the spectrum produced by clock mechanisms. It describes the experimental setup, results, and conclusions drawn from the investigation. A filter is presented which appears to be capable of increasing the signal-to-noise ratio of the detected signal.
