Please help me with Question4 on the attached pdf file.
An access control system to enter a higly secret Physics Laboratory consists of a card reader,
a keypad and an eye retina recognizer. The system controls the opening of two doors that lead
to special experiments labs. However, if the system recognizes a dangerous situation may
release into the air a chemical substance to make the person faint or release a sharp lever that
will kill the person.
We want to design the access control system circuit. If the person has the correct card and eye
retina and if the person types in the correct password code then the person will be able to have
one of the doors open to the labs, otherwise the person will be in terrible danger! See Figure 2.
The outputs from the card reader are as follows:
Hi dcheon. I've found that it's a complex circuit. Yet, I've try to make it easy to... View the full answer
