Abstract
In this paper we propose to present the pulse mode asynchronous sequential systems implementation method. On the system input we have digital level input signals and pulses signals inputs. During the pulses inputs are generated, the digital level input signal must remain constant ( 1 or 0). If it changes it's value during the pulses occurrences, the system may fail. To generate de pulses signals we use relays switchers.The proposed algorithm can be successfully implemented in vending machines automata.
