Abstract: An A/D converter provides a high conversion accuracy even when an input analog signal is at a low level. The A/D converter (10) comprises a first line including a first A/D conversion unit (ADC1) connected to an input terminal (1) applied with an analog signal, a second line including a first amplifier (AMP1) connected to the input terminal (1) and having an amplification ratio of 2m (m > 0), a second A/D conversion unit (ADC2), and a second amplifier (AMP2) having an amplification ratio of 2-m, and a combination of a switch and a level detector (SW, LDET) for connecting an output of the first line or an output of the second line to an output terminal (2) in accordance with an output level of the first line.

Abstract: Provided are a quantification method and a quantification device with which it is possible to measure a sodium -ion- containing sample , such as a biological sample, a pharmaceutical product or food , with high sensitivity and high accuracy. This quantification method comprises: a calibration curve creating step for measuring a standard solution, which has been prepared by adding sodium ions such that the sodium ion content thereof is equivalent to the sodium ion content of a sample to be measured in accordance with a method employing a reaction that activates a Limulus reagent and/or a biochemical luminescent reaction caused by ATP ,luciferin, and luciferase , and for creating a calibration curve that represents the relationship between the measurement value and the amount of a component to be measured; a sample measurement step for measuring said sample to be measured in accordance with the same method as the method used in said calibration curve creating step; and a quantification step for finding , by using said calibration curve , the amount of said component to be measured in said sample to be measured from the measurement value obtained in said sample measurement step.

Abstract: Digital audio data with error detection bits added thereto is inputted to an error detecting and correcting device (4). The correcting device (4) corrects an error when the error is detected in the digital audio data. The digital audio data outputted from the error detecting and correcting device (4) is inputted to an impulse noise suppressing circuit (6). The suppressing circuit (6) operates for a predetermined time period when the correcting device (4) detects an error.
