Abstract
본 발명은 종래의 텔레비젼에서 음량레벨의 설정등 아날로그 컨트롤시에 그 조정단계가 너무 커서 미세조정을 할 수 없었던 문제점을 해결하기 위해 발명된 것으로, 미세조정 모드가 시청자에 의해 선택되는 경우에 PWM발생부에서 생성되는 펄스신호의 발진주파수를 낮아지도록 구성하는 바, PWM신호의 주파수를 낮추게 되면, 이 PWM신호를 적분하여 얻어지는 아날로그 신호의 변화폭을 미세하게 가변할 수 있게 되며 이에 따라 종전과는 달리 미세한 아날로그 컨트롤이 가능하도록 구성한 것을 특징으로 한다.The present invention has been invented to solve the problem that the adjustment step is too large for analog control, such as setting the volume level in a conventional television, so that fine adjustment cannot be made. In the case where the fine adjustment mode is selected by the viewer, PWM is generated. It is configured to lower the oscillation frequency of the pulse signal generated by the negative. When the frequency of the PWM signal is lowered, the change range of the analog signal obtained by integrating the PWM signal can be changed minutely. It is characterized by being configured to enable analog control.
