| Abstract: | Three aspects regarding the operational precision of a digital noise reducer, namely, theoretical analysis, software simulation and actual test on the hardware system, are studied. The relationship between operational precision and system performance is discussed. The design principle for the hardware system is proposed and the system structure is optimized to give a fair compromise between hardware expense and system performance. |
