1. In an electronic system having a position encoding circuit having a manually adjustable position encoder connected to a target circuit and used to control an audio or a video function of said electronic system, said position encoder having a rotatable element capable of being continuously rotated through an angle of greater than 360 degrees in either direction, said position encoding circuit transmitting, to said target circuit, an encoder position signal indicative of said rotational displacement of said rotatable element, said position encoding circuit having a virtual preset point which is a rotational position of said rotatable element corresponding to a predetermined value of encoder position signal, an apparatus for locating said virtual present point for said position encoder comprising:

  • storing means for storing and outputting data indicative of said virtual preset point; and

    processing means for1) comparing said encoder position signal and said data output by said storing means indicative of said virtual preset point and2) setting, for a predetermined time interval, said encoder position signal equal to an encoder position signal indicative of said virtual preset point, when said processing means determines that said rotatable element in said position encoder has been rotated past said virtual present point.
