Bus system for conduction bound transmission of discrete value information signal between transmission receive circuit has reference power source with transmission circuit for generating reference circuit, reference line, evaluation circuit

摘要

Bus system has reference power source (104.3) containing transmission circuit (101) for generating reference circuit. The reference circuit is transmitted over reference line (109) for receive circuit (102). The evaluation circuit (TIA1,TIA2,106) receives the reference circuit over the reference line compares it with the current and generates output signal (OUT) depending on the reference output. An independent claim is also included for the method for conduction bound transmission of discrete value information signal.
