Abstract: PURPOSE: A gain control system for generating high quality digital data is provided to obtain a large gain corresponding to an environment, thereby heightening the quality of generated digital data. CONSTITUTION: An analog signal input unit(1100) receives an analog signal. A gain processing unit(1200) controls gain of an analog-digital converter(ADC). The ADC(1300) converts analog signal handled with gain into a digital signal. A digital data output unit(1400) outputs a converted digital signal. The gain processing unit includes a step(A) of setting gain as a predetermined level of the first gain; a step(B) of sensing peak generation during an analog-digital conversion process; and step(C) of determining a necessity of gain decreasing regulation by inspecting peak generation in step(B). The gain processing unit includes a step (D) of lowering the gain to the second gain level lower than the first gain level, decreasing by a predetermined gain decrease unit.

Abstract: 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.
