Abstract
A circuit adjusts the gain, direct-current (DC) component, and transient response of input signals to provide suitable output signals for a connected signal processor. The circuit includes a gain and DC component control circuit, which controls the amplitude and DC offset level of an input signal; an A/D converter, which performs A/D conversion on the output of the gain and DC component control circuit; and an equalization filter, which is connected to the output of the A/D converter. The amplitude distribution of the output waveform of the equalization filter is measured, and the gain and DC component control circuit is controlled on the basis of said measured value, in order to assure that the output of the equalization filter is suitable for a connected signal processor.
