1 Objectives Bar codes are used anywhere and everywhere. The USPS also uses codes at the bottom of envelopes for easier sorting. After this lab, we will be able to convert a specific input from a hex keyboard into a 2-Out-Of-5 code; this is the code which the USPS uses. 2 Background Bar codes all around the world use different lengths of line to determine the meaning of what it displays. Each different length of line means something different as shown in the experiment. In the USPS, the lines at the bottom of each envelope display the zip code of the address to where it is being sent. Using this code translation, one can efficiently organize mail being delivered with the correct program. 3 Procedure In this section we will explain how exactly to design the necessary tables and circuits to complete the lab. 3.1 Creating Tables To begin the experiment one must first create a table of the binary values from one to nine. Afterwards it is necessary to convert these binary values into POSTNET values.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
