闭环

Virtual haptical system is a circulate feedback closed loop, including bidirectional information transfer between virtual and really environment.

虚拟触觉系统是一个触觉信息循反馈的闭系统,其中包含着虚拟与现两者之间向的信息传递。

This paper presents an all-digital close-loop operation based on DSP circuits, which uses the two-frequency serrodyne modulation to modulate and demodulate the optic route.
