ABSTRACT:
An apparatus adaptable for use with a digital-analog conversion device for effecting communications from a digital device to an analog device, having a digital-analog circuit for converting interpolated outgoing digital signals to outgoing analog signals. The apparatus further has a digital signal processing circuit for interpolating outgoing digital signals received from the digital device and providing an interpolated outgoing digital signal to the digital-analog device. The digital signal processing circuit is comprised of a plurality of modules which are configured so that a specified set of the plurality of modules effects a specified number of iterations of interpolation. The modules are further designed so that additional modules may be added to the specified set of modules to increase the iterations of interpolation.
