An electronic memory system and method for use in a system for reducing quantizing noise is presented. In some Internet access and other dial-up services, modems or other sources connect into analog switching systems, and then are A/D-converted to reach remote switching offices. There, the digitized signal is converted back to analog, only to be re-digitized for T1 transmission. In the invention, the sample points used to re-digitize the signal are encoded using a dedicated electronic memory structure which permits efficient determination of valid data points.
