DEMULTIPLEXER APPARATUS AND COMMUNICATION APPARATUS USING THE SAME

摘要

A demultiplexer apparatus includes a plurality of series-connected integrators (10). The plurality of integrators receive serial binary data. A current-stage one of the plurality of integrators converts the serial binary data into a multilevel data, and produces a restored data based on both that multilevel data and a restored data produced by the integrator of the immediately preceding stage. The plurality of integrators output these produced restored data as parallel binary data relative to the forgoing serial binary data. In this way, there is provided the demultiplexer apparatus that can precisely read data having a frequency component that exceeds the maximum operational frequency.
