Abstract
A dematrixing processor for an MPEG-2 multichannel audio decoder, which is capable of performing a decoding matrix process with respect to five compositely decoded signals to restore them to their original status. To this end, the dematrixing processor comprises an arithmetic/control logic unit for performing a dematrixing operation with respect to the five compositely decoded signals to restore them to their original status, and an IIR filter for low pass filtering an output signal from the arithmetic/control logic unit and providing the low pass filtered result to the arithmetic/control logic unit.
