Abstract
Analog data is collected by conversion to a digital representation thereof via an analog to digital converter. Reference voltages for the converter are provided by digital to analog converters. The reference voltages are varied under the control of a central processing unit to establish a range of interest in the analog data. The range of interest is narrower than the conversion range of the analog to digital converter.
