Abstract: Disclosed is an apparatus to process an electric wave signal utilizing a transputer. The apparatus comprises a host computer, a central processing means, a receiving means, a frequency converting means, an analog to digital converter, a band dividing means, many digital signal processors and a transputer network. The central processing means controls operation of frequency receiving to determine whole scanning frequency band which is setted by the host computer. The receiving means receives the frequency according to control of the central processing means. The frequency converting means converts the frequency from the receiving means to be in the low band. The analog to digital converter converts the output of frequency converting means into a digital signal. The band dividing means divides the output of analog to digital converter into many bands. The digital signal processors performs the Fast Fourier Transform with the band signals from the band dividing means. The transputer network parallely processes the signals from the digital signal processors, and sens to the processed signals to the host computer. Thereby, the frequency converters can be reduced, band can be simply extended by the transputer network, and the processing time can be reduced.

직렬덧셈기 제어로직의 제어를 받는 직렬덧셈기는 상기 직렬데이타를 입력받아 각 비트단위로 소정갯수의 데이타를 합하고, 이 합산값은 레지스터에 임시로 저장되었다가 디지털/아날로그 변환기로 인가되어 아날로그 신호로 변환된다.
따라서, 지연시간 및 아날로그 공통카드로 입력되는 라인수를 현저히 줄일 수 있는 효과가 있다.-
