In this learning journal assignment, you will design a smart home electronic security system utilizing combinational circuits, including logic gates, multiplexers, decoders, and encoders and describe the integration of each component to control room access via code or keycard.

Scenario:

Imagine you are working as an intern at a tech company specializing in electronic devices. As part of your training, you have been given the task of designing a simple electronic security system for a smart home using combinational circuits. The security system should be able to control access to different rooms in the house and allow authorized users to enter using a code or keycard.$$

$1.$ Compose a design for the electronic security system using logic gates, multiplexers, decoders, and encoders.$$

$2.$ Explain how each component will be incorporated and how they will work together to achieve the desired functionality.$$

$3.$ Enhance your design by summarizing how you could integrate a demultiplexer into the system to handle multiple rooms' access control efficiently.

Use sources to support your arguments. Add a reference list at the end of the submission. For assistance with APA formatting.
