    Synchronous counter digital clock

    If you want to know how to do it yourself, and are willing to take the time, go through https://www.physicsforums.com/showthread.php?t=100628". I assume you understand basic logic. KLM

    What are the challenges faced by female engineering students?

    I say 'go for it'. Sure, there will be male sexism in school, but what I have found out is that it is usually used to cover-up fears of inadequacy on the part of those who make the most bluster. Rarely do the really top students behave in that manner. In fact, they are usually willing to work...

    Karnaugh Maps: An Essential Tool for Understanding Complex Digital Logic Designs

    Yours are wonderful observations, but I couldn't disagree more. First, if you've followed these insertions, minimization itself is not the main thrust. The main use is to define logic relations that accomplish the desired tasks without design blow-ups. Little attempt was made to determine...

    International Companies Embrace Innovative Ideas, U.S. Companies Not So Much

    http://news.cnet.com/8301-11128_3-20061822-54.html?part=rss&subj=news&tag=2547-1_3-0-20" seems like an interesting idea. I don't know how well it will pan out, but I find it interesting that U.S. companies rejected it out-of-hand, whereas companies elsewhere were more receptive. This I have...

    Designing 8-bit Binary to BDC Converter

    Very clever. Rather than trying to convert, just recount the value. It will definitely work, though I'm not exactly sure what the instructor might think of it. Imagine the time to convert 32-bit numbers. By the way; I tested what I described earlier and it works perfectly (after numerous...

    Designing 8-bit Binary to BDC Converter

    Thanks for the "heads up". I certainly don't intend to violate the rules, and will not post answers here - - just possibly suggestions, and how I have progressed. (Actually, I cannot post diagrams here, even if I wanted to.) KM

    Designing 8-bit Binary to BDC Converter

    Chroot was right that using the Double Dabble approach would be complicated, if conventional thinking is employed; however, some shortcuts may be possible. I’ve noted a couple of possible provisions, using the Double Dabble approach whereby the process appears to become much simpler - - if...

    How Can I Implement an Add 3 if Greater Than 5 Function Using Only NOT Gates?

    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. KLM

    How Can I Implement an Add 3 if Greater Than 5 Function Using Only NOT Gates?

    I want to say that I have a (reasonably) finished sample of the conventional decimal to BCD converter (32 bit), finally, after it took a bit longer than planned (for several reasons) and a week-long delay caused by the yearly call of socialism. I also have a problem; in that I have run out of...

    Karnaugh Maps: An Essential Tool for Understanding Complex Digital Logic Designs

    Six variables horizontally, and four vertically. This would take probably at least an 11" X 17" sheet and a lot of work (both the drawing and the use). I have done it so I know. Sorry it took this long. KM

    How Can I Implement an Add 3 if Greater Than 5 Function Using Only NOT Gates?

    I am putting together an alternative; a straight decimal to BCD converter, not using the described "algorithm" approach. I will attempt to send it directly to you through PF. They have a method, if you accept it. It will probably be ready in about three days. KM

    How Can I Implement an Add 3 if Greater Than 5 Function Using Only NOT Gates?

    http://www.datasheetcatalog.org/datasheets/400/331354_DS.pdf" is a datasheet for a quad two to one mux. It is an old TTL implementation, but it shows the logic. Notice that it has two control inputs. The select input has two inverters in-line. This just provides buffering; one could do but...

    How Can I Implement an Add 3 if Greater Than 5 Function Using Only NOT Gates?

    I am not certain of what the "ROMs" are being used for. KM

    How Can I Implement an Add 3 if Greater Than 5 Function Using Only NOT Gates?

    If someone could arrange for more downloads, or to offload the Karnaugh Map series to another site, I would be able to put in more. KM

    How Can I Implement an Add 3 if Greater Than 5 Function Using Only NOT Gates?

    I apparently have no attachments left to upload, so I can't show it. Basically, each of the (four) selectors is made up of two ANDs into an OR. The "A" side signal goes to one AND and the "B" side signal to the other. The "control" signal goes directly to one AND and through an inverter to the...
