Abstract

An incremental digital converter for converting two phase-displaced position signals from a pulse generator (3) representing the position and direction of an object (11) movable in two opposite directions to a parameter representing the position digitally. The converter comprises a reversible position counter (6) and a signal generator (4) which derives a direction signal (R) determining the counting direction of the position counter (6) and timing pulses to be counted by the position counter. The signal generator includes a flank detector (22) deriving a timing pulse (T) from each flank of the position signals and a direction discriminator (21), to which the timing pulses (T) of the flank detector (22) and the position signals (A, B) can be fed to produce the direction signal (R). The direction discriminator comprises a first D flip-flop (24) to the D input of which the one position signal (B) is fed via a delay element (25), a second D flip-flop (23) to the D input of which the other position signal (A) is fed directly and a logic combination circuit (27) following the two D flip-flops (23, 24), the flank detector (22) producing a timing pulse (T) at each flank of each position signal (A), and the pulses ofthe flank detector being fed to the timing inputs (C) of the D flip-flops (23, 24). <IMAGE>
