METHOD OF MINIMIZING DIGITAL PEAK, CAPABLE OF SEEKING OUT GAIN WHICH IS SUITABLE FOR CORRESPONDING ENVIRONMENT WHILE PASSING ADOPTION TIME

摘要

PURPOSE: A method of minimizing digital peak is provided to ignore meaningless peak which is mostly not recognized to people, thereby secure large gain corresponding to environment.;CONSTITUTION: Gain is set up as the predetermined first gain level(S11). Generation of peak is sensed during an analog-digital conversion process(S12). Necessity of reducing the gain is determined by inspecting the peak generation(S13,S14). When necessity of the gain reduction is determined, the gain is decreased to the predetermined gain regulation width in the second gain level, which is lower than the first gain level(S15). Until gain reduction is decided to be unnecessary, the steps are repetitively performed.;COPYRIGHT KIPO 2013;[Reference numerals] (S11) Setting up gain as a first gain level; (S12) Sensing the generation of peak; (S13) Checking a gain control policy by the sensed peak generation information; (S14) Determining the necessity of controlling the gain; (S15) Reducing the gain as a second gain level; (S16) Maintaining the set gain
