Introduction

The implementation of security systems is seen as a very important element in our societies nowadays. Whether it is our home or office we have a certain measure of security .

The aim of this technical note is :

• To show a simple implementation of a security systems using ROM and D-type flip-flops , an example of a simple sequential system.
• To describe the voltage and current characteristics of TTL gates.
• To design and construct minimised Boolean expressions using NAND-only and NOR-only circuits.
  

The implementation of the security system in this technical note is going to be divided into the :

• Specification phase
• Design and Implementation phase
• Design and Implementation phase
• Construction and Testing phase

The Follow-up experiments is included to the understanding of the TTL gates and NAND-only and NOR-only circuits.
