Abstract:
A signal level adjustment apparatus includes a detector configured to detect both a plurality of peak levels of an input signal having a sinusoidal waveform or a substantially sinusoidal waveform and a plurality of bottom levels of the input signal; and a level adjuster configured to adjust, in a predetermined zone of the input signal, levels of the input signal based on the plurality of peak levels and the plurality of bottom levels detected by the detector.
