Synthesis of Combinational Logic Circuits (9)
Example 2.41: A burglar alarm with four control switches, each of which produces logic 1 when:
Switch A: Secret switch is closed
Switch B: Safe is in its normal position in the closet
Switch C: Clock is between 1000 and 1400 hours
Switch D: Closet door is closed.
Write the equations of the control logic that produces logic 1 when
the safe is moved AND the secret switch is closed,
OR
the closet is opened after banking hours,
OR
the closet is opened with the control switch open.
