AUDIO SIGNAL REGENERATING DEVICE

摘要

PURPOSE:To obtain an audio signal regenerating device in which a sound quality preferable in a listening sense is obtained by compensating a missing frequency component at an inaudible band. CONSTITUTION:An adder 14 adds a very small sine wave signal 'c' from an attenuator 12 and a DC offset signal 'd' from an attenuator 13. A multiplier 15 multiplies a sum signal 'e' and an audio signal 'g' from which a frequency component at an inaudible band is eliminated to produce an output signal having a frequency component at an audible band.
