Abstract:
    A signal level adjusting apparatus comprises an amplifier that amplifies an input signal with a gain of a first gain value and outputs an amplified signal; a gain calculator that obtains a second gain value according to a signal level of the input signal; and a gain updater that updates the first gain value stepwise such that the first gain value approaches the second gain value by steps corresponding to an error between the first gain value and the second gain value.
