Abstract

PURPOSE:To eliminate noise included in a digital signal outputted from an analog/digital converter by setting a threshold level in a frequency spectrum of a digital signal to a zero level of the frequency spectrum of the digital signal. CONSTITUTION:A small level signal under a threshold level in the frequency spectrum in a digital signal outputted from an A/D converter 24 is eliminated by a noise suppression means 10. Then the threshold level is set to the zero level of the frequency spectrum of the digital signal, and the result is fed to a digital signal processing means 18, where various signal processings are implemented. Thus, the noise included in the digital signal outputted from the A/D converter 24 is eliminated.
