Abstract: A fixed member and a movable member are provided together with means for providing a cyclic wave pattern upon moving the movable member relative to the fixed member. The direction and precise extent of movement are determined by observing the pattern and the extent is indicated as a digital readout. Comparatively inexpensive components are used to determine and indicate the major portion of the digital readout. Logic means is employed for determining at least one digit, such as the least significant digit, of the readout using electrical signals in a substantially static condition whereby such digit is determined absolutely and independently of any previous movement of the movable member.
