Zusammenfassung:	PCT No. PCT/EP88/00407 Sec. 371 Date Jan. 6, 1989 Sec. 102(e) Date Jan. 6, 1989 PCT Filed May 10, 1988 PCT Pub. No. WO88/09481 PCT Pub. Date Dec. 1, 1988.When signals from an incremental transmitter are being evaluated, noise may distort the signals and the subsequent stages connected to the transmitter may therefore be incorrectly controlled. The invention discloses a process for suppressing the noise, thereby permitting correct evaluation. In the process, the signals at the outputs of the incremental transmitter are sampled at high frequency and stored in an intermediate store. They are then checked to ascertain whether a predetermined sequence of output signals exists. Since this predetermined sequence is not respected in the event of interferences, no signal is produced. A signal is produced only when the predetermined sequence is respected. The process can be applied wherever it is desired to obtain an undistorted output signal using an incremental transmitter of simple design.
