Abstract

적어도 하나의 버팀봉에 맞대어 현을 누름으로써 진동길이가 변화될 수 있는 적어도 하나의 인장된 현(E1, H2, G3, D4, A5, E6)을 가진 시그널 분석장치(1)에 관한 것이다. 또한 상기 장치는 픽업(2)및 상기 픽업에 연결된 평가장치(3 내지 9)를 구비하고 있다. 본 발명의 목적은 현의 자극이후에 바람직한 음조 데이타를 비교적 신속히 제공하는 기타 합성기를 제공하는 데에 있다. 평가장치(3 내지 9)는 상기 현(E1, H2, G3, D4, A5, E6)의 자극에 이어서, 상기 픽업(2)을 통과하는 현을 따라 지나는 펄스 또는 펄스 그룹을 검출하고, 상기 순차 펄스 또는 순차 펄스 그룹으로부터 음조를 나타내는 신호는 발생하므로 이에 의해 상기 목적이 달성된다.

Claims (6)

  1. 팽팽한 현의 진동가능한 길이가 하나의 구축물을 통하여 최소한 하나의 프레트 쪽으로 변화할 수 있는 최소한 하나의 팽팽한 현과 하나의 픽업, 그리고 픽업이 결합된 평가장치를 갖춘 시그널 분석장치에 있어서, 평가장치는 연주과도파들로 형성된 임펄스들이나 현(11)의 자극이후 픽업(2)에 위치한 현(11)위를 지나가는 임펄스 그룹들을 파악하고, 임펄스 그룹의 진행시간을 현 위에서 평가하고, 개별적인 임펄스들이나 임펄스 그룹사이의 진행시간 내지는 진행시간 차이를 토대로 하여(제3 도) 음높이를 나타내는 하나의 시그널을 만들어 내는 것을 특징으로 하는 시그널 분석장치.
  2. 제1항에 있어서, 평가장치는 임펄스들이나 임펄스 그룹들의 양극성을 파악하고, 임펄스들이나 임펄스 그룹들의 시간적 연속적으로부터 현(11)의 자극위치(17)를 나타내는 하나의 시그널을 찾아내는 것을 특징으로 하는 시그널 분석장치.
  3. 제1항 또는 제2항에 있어서, 평가장치는 임펄스들이나 임펄스 그룹들에 대한 각각의 연속을 어떤 다수로부터 한 부류로 분류하는 신경망(5)을 나타내는 것을 특징으로 하는 시그널 분석장치.
  4. 제3항에 있어서, 평가장치는 진동하는 상태에서 현(11)으로부터 얻어진 음높이-시그널과 임펄스-연속으로 얻어진 시그널을 비교하고, 예정된 수치를 넘어서는 이탈시에 신경망(5)의 학습 알고리즘을 푸는 비교장치(8)를 나타내는 것을 특징으로 하는 시그널 분석장치.
  5. 제3항 또는 제4항에 있어서, 임펄스 그룹들로부터 개별적인 임펄스들을 선별하는 선별장치(6)가 신경망(5)에 우선적으로 접속되는 것을 특징으로 하는 시그널 분석장치.
  6. 제1항 내지 제5항중의 어느 한 항에 있어서, 각각의 현(11)에 있어서 자신의 고유한 픽업(2)이 고려되어 있는 것을 특징으로 하는 시그널 분석장치.
