System zur Steuerung einer graphischen Maschine

摘要

The system has a transmitter and receiver module (2) for handling acoustic communication signals and is coupled to hardware (1) that suppresses noise and provides an analogue output. A generated pulse signal is superimposed and the modulated signal is received and demodulated followed by processing (3) and input to a speech interpreter (5), verifier (6), logic (7). Any fault conditions are signalled and displayed (15).
