摘要：The system comprises a data bit source (1) with a single bus line (3) connectedto its data output (2). A data bit series comprises a start bit and a specific number of databits. The start bit has a trailing edge, the data bits a leading edge. The bit value of a databit is characterised by the length of the pulse with which the data bit begins. An
instruction decoder (4) samples every bit with a sampling pulse of a clock pulse counter(10) generated at a specific counter reading (z8), this counter being incremented by thepulses from a clock pulse source (11) and controlled by an edge detector (12). The databit values which are written into a data bit memory (18) at the sampling times areconverted at the end of the data bit series in an instruction memory (20) into controlsignals (S7) corresponding to the stored instruction. The clock pulse frequency of theclock pulse source (11) does not need to be precisely defined.
