摘要： An analog-to-digital converter includes a track hold circuit, a reference voltage generating circuit, a switched capacitor circuit, a preamplifier that amplifies a voltage held by the switched capacitor circuit, a comparator that generates a logic level corresponding to an output from the preamplifier, and an encoder that converts the logic level into a binary code (n-bit digital output). If capacitors constituting the switched capacitor circuit are charged and the charges in these capacitors then vary, each capacitor is recharged by an amount corresponding to the particular variation.

摘要： According to one embodiment, a sound corrector includes a signal outputter, a response signal, a frequency specifier, a coefficient specifier, a filter, and an outputter. The signal outputter outputs a measurement signal to measure acoustical properties of an object to be measured. The response signal receiver receives a response signal from the object in response to the measurement signal. The frequency specifier specifies a resonant frequency at a resonance peak from the response signal. The coefficient specifier specifies a correction coefficient of a correction filter for reducing the resonant frequency based on the specified resonant frequency. The filter performs filtering on a signal to be output to the object using the correction filter with the correction coefficient. The outputter outputs the signal having undergone the filtering to the object.
