The central bank has a vault controlled system for nine (9) vaults in its care. An ant-theft system is put in place to protect the vaults. A vault has eleven (11) lock controller inputs which are synchronized with a clock input. At any one time only one lock vault controller should be open on a vault, otherwise an ALARM should be sent such that ALL vault alarms are triggered and an update sent to the VAULT monitoring station. Show the design assumptions that control all nine (9) VAULT electronic circuit systems as one integrated circuit.
