Abstract

A transmission line based bowed string model is built by analogizing a vibrating string to an electrical transmission line and implementing the calculation for the frictional bow-string force given by a digital bow into a circuit. The performance of the proposed model is demonstrated by showing that the velocity of the string at the bowing point from the proposed model is consistent with that from the finite difference form of the wave equation for a bowed string by the digital bow.

진동하는 현을 전기적 전송선로에 비유하고 디지털 활에 의해 주어지는 활과 현간 마찰력에 대한 계산을 회로로 구현하여 전송선로 기반 찰현 모델을 구축하였다. 제안된 모델의 성능은 활이 현에 접촉하는 위치에서 현의 속도가 찰현에 대한 파동방정식의 차분형식(finite difference form)으로 구한 속도와 일치함을 보임으로서 증명하였다.
