Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

The author describes a low-cost battery-powered instrument based on the c-mos Motorola MC146805 E2P microprocessor. In this instrument the input is sampled repetitively and compared with a table of values stored in memory, so that over time, a distribution of the sampled input is built up in 21 internal memory channels (20 channels plus 1 'over-range' channel). The program controlling the microprocessor can be adapted to suit different needs by simply changing the values stored in this table, and/or by changing the measuring period.
