SUMMARY

This discussion focuses on implementing an "Add 3 if Greater Than 5" function using only NOT gates for an 8-bit adder project. The user is constrained by their design environment, which only allows NOT gates, making the task challenging. They explore various methods to create a comparator and adder logic, referencing the TI CD4585B comparator and discussing the limitations of using NOT gates for complex logic. The conversation also touches on binary multiplication and the need for a deeper understanding of digital logic design.

PREREQUISITES
  • Understanding of digital logic design principles
  • Familiarity with binary and BCD (Binary-Coded Decimal) conversion
  • Knowledge of comparator circuits, specifically the TI CD4585B
  • Basic skills in using logic simulation software
NEXT STEPS
  • Research methods for binary to BCD conversion using discrete logic
  • Learn about the functionality and implementation of the TI CD4585B comparator
  • Study binary multiplication techniques and their application in digital circuits
  • Explore logic simulation software alternatives for designing complex circuits
USEFUL FOR

Electrical engineering students, hobbyists in digital logic design, and anyone interested in creating circuits with limited components.

Hi again Kenneth!

If you want, you can e-mail the pictures to me and I'll upload them to my website. I'll just shoot their address to you, and you can link them in your posts. Give a little bit, and I'll see if I can set up ftp access for you, and you can just start using my site without the need of e-mailing me.

Don't worry about file size, or bandwidth, as it's an unlimited dedicated server.

I'll PM you my e-mail address.

I uploaded the working circuit on the "http://www.logiccircuit.org/forum/viewforum.php?f=4"" website. See if you can download it and get it to work. I included simple user instructions, but there is more you may want to look into. I still hope to put pictures on the PF website.
