Abstract

본발명은 물리적 접촉 열이 신호전송이 가능한 전자유도에 의한 디지탈신호 전송회로에 관한 것으로, 신호발생 회로(10)에서 생성된 사인파와 디지탈신호부(60)에서 발생된 구형파를 혼합회로(20)에서 중첩하여 증폭회로(30)를 통해 중폭되어 무선으로된 신호전송부(40)를 경유하여 정류회로(50)에서 사인파를 제거한후 구형파만을 출력시켜 오차율을 줄일수 있는 발명이다.The present invention relates to a digital signal transmission circuit by electromagnetic induction capable of transmitting a physical contact signal, the sine wave generated in the signal generation circuit 10 and the square wave generated in the digital signal unit 60 is mixed circuit 20 In the invention, the sine wave is removed from the rectifying circuit 50 via the signal transmission unit 40 which is overlapped by the amplification circuit 30 and wirelessly, and only the square wave is output to reduce the error rate.
