Claims (1)

마이크(MIC)의 입력신호를 필터(LPF1)를 통과케하여 샘플/홀드부(S/H)를 거쳐 A/D 컨버터(A/D)에서 디지탈신호로 바꾼다음 버퍼(BF1)와 디코더(DC)에 의하여 디에스피칩(D.S.P)에 제공하고 디에스피칩(D.S.P)은 롬(ROM)과 램(RAM)의 어드레스 지정에 따른 데이타를 버퍼(BF2)를 통과시켜 D/A 컨버터(D/A)에서 아날로그신호로 변환시키고 이를 필터(LPF2) 및 스피터(SP)에 의하여 연산된 음성신호를 제공할 수 있게 함을 특징으로 하는 음성신호를 이용한 계산기.The input signal of the microphone MIC is passed through the filter LPF 1 and converted into a digital signal from the A / D converter A / D through the sample / hold part S / H, and then the buffer BF 1 and the decoder. The DC chip is provided to the DSP by the DC, and the DSP transmits the data according to the addressing of the ROM and the RAM through the buffer BF 2 to the D / A converter D / A. A) A calculator using an audio signal, characterized in that for converting to an analog signal and to provide the audio signal calculated by the filter (LPF 2 ) and the SP (SP). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
