Abstract:
An absolute value transmitter, comprising:a transmitter component including a coding having a predetermined number n of locally sequential digital words (W.sub.i), each having a width of m individual bits (b.sub.1, b.sub.2, . . . b.sub.m) in adjacent tracks;at least one detector simultaneously registering the individual bits (b.sub.1, b.sub.2, . . . b.sub.m) defining one of the digital words (W.sub.i), the transmitter component being movable with respect to the at least one detector; andan evaluation unit for receiving respective signals from the at least one detector and determining an absolute position of the transmitter component relative to at least the one detector, at least for a first time, by evaluating a predetermined number p of the sequentially detected digital words (W.sub.i), the evaluation unit assigning to a detected p-tuple (W.sub.i, W.sub.i+1, W.sub.i+p-1), including a predetermined number p of the sequentially detected digital words (W.sub.i), a defined position value of the transmitter component relative to the at least one detector, all of the sequences (W.sub.i, W.sub.i+1, W.sub.i+p-1) from the predetermined number p including the sequential words (W.sub.i) being uniquely defined within at least one predetermined uniquely defined area (I, II) of the coding, and the digital words (W.sub.i) not being uniquely defined within each of the at least one uniquely defined areas (I, II).
