Communications interface apparatus.

摘要

An apparatus adaptable for use with an analog-digital conversion device (14) for effecting communications between an analog device (12) and a digital device (24), the analog-digital conversion device converting incoming analog signals received from the analog device to incoming digital signals. The apparatus has a digital signal processing circuit (18) for decimating the incoming digital signals and providing a decimated incoming digital signal to the digital device. The digital signal processing circuit is comprised of a plurality of modules (19) which are configured so that a specified set of the plurality of modules effects a specified number of iterations of decimation. The modules are further designed so that additional modules may be added to the specified set of modules to increase the iterations of decimation.
