Claims (1)
- 수직출력신호 입력단(1)을 제너다이오드(ZD11), 접지콘덴서(C11) 및 다이오드(D11)를 통해 저항(R12)에 접속함과 아울러 그 접속점에 수평출력신호 입력단(2) 및 수직동기신호 입력단(7)을 저항(R11) 및 다이오드(D12)를 각기 통해 공통접속하여, 그 접속점을 병렬접속된 콘덴서(C12) 및 저항(R13)을 통해 트랜지스터(TR11)의 베이스에 접속하고, 그 트랜지스터(TR11)의 콜렉터를 전원단자(B+)측 및 연산증폭기(8)의 비반전입력단자에 접속하여, 그의 출력단자를 저항(R16)을 통해 저항(R15) 및 그의 반전입력단자에 접속함과 아울러 그 출력단자를 저항(R18) 및 제너다이오드(ZD12)에 접속한 후 병렬저속된 저항(R19) 및 콘덴서(C13)을 통하고 저항(R20)을 다시 통해 콘덴서(C14) 및 그리드(G1)에 접속하고, 양단자측에 전원단자(V-),(V+)가 접속된 가변저항(VR11)의 가변단자를 저항(R21)을 통해 상기 저항(R19,R20) 및 콘덴서(C13)의 접속점에 접속하여 구성된 것을 특징으로 하는 수직 수평 블랭킹 보호회로.
