ABSTRACT:
An evaluation arrangement for a digital incremental transmitter of the type wherein two phase-shifted sinusoidal voltages of the same period are produced generates a periodic triangular voltage signal which is subsequently converted to digital values. The digital values are produced in response to an interlinking of linear portions of the sinusoidal voltages. The digital values are used to address a read-only memory in which are stored a plurality of absolute values within a period.
