Abstract
A power saving system and method for the analog-to-digital converter stage in a time of flight ranging system. A receiving echo signal having an envelope is converted into a digital form suitable for further processing by sampling the received echo signal envelope at precise intervals to obtain amplitude measurement points. An interpolation function is applied between each pair of adjacent amplitude measurement points. The application of the interpolation function provides a closer approximation of the shape of the received echo signal envelope without the need to use higher sampling rates which means slower analog-to-digital converters may be utilized resulting in power and cost savings.
