ABSTRACT:
An apparatus adaptable for use with an analog-digital conversion device for effecting communications between an analog device and a digital device, 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 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 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.
