Abstract
Description
Claims (2)
- 전자악기에 이용되는 포락선 발생회로에 있어서, 두 종류의 포락선 발생을 제어하기 위한 타이밍제어부(1)와, 이 타이밍제어부(1)의 제어를 받아 계단파를 발생하는 스위치부(2)와, 이 스위치부(2)에서 출력되는 계단파중 고역주파수 성분만 통과시키는 고역통과여파기(3)와, 상기 타이밍제어부(1)의 제어에 의해 포락선 발생전원을 스위칭하는 전원스위치부(4)와, 이 전원스위치부(4)의 출력전압전위를 유지하는 샘플앤드홀드부(5)와, 상기 타이밍제어부(1)의 제어를 받아 상기 고역통과여파기(3) 또는 샘플앤드홀드부(5)의 출력신호를 선택하여 출력하는 파형선택스위치부(6)로 구성하여된 것을 특징으로 하는 포락선 발생회로.
- 제1항에 있어서, 상기 전원스위치부(4)는 상기 타이밍제어부(1)의 제어를 받는 스위치(SW2)의 고정단자(a1), (a2), (a3)를 전원단자(Vcc), 접지저항(R3), 접지에 각각 접속하여 구성함을 특징으로 하는 포락선 발생회로.
