    Semiconductor light-emitting diodes

    This might require more research, but isn't a diode a current-controlled device? MLH

    Compare Branch and Jump Instructions for Computers

    It also sometimes has to do with language you are programming. I believed in 68HC11 code, a jump is for an absolute position, and a branch is relative. Check out the BRA and the JMP commands. From what I have seen, it is more loose than an absolute definition. -- MLH

    What is the issue with log scales and plotting values less than 1?

    can you post the code? I have an idea, but don't know if it defeats the purpose or not. Would flooring the result be a work around? Matt

    Will an Op-Amp Output Maximum Voltage with V+ Connected to I+ and V- to I-?

    Ok, I just want to see if this would work (but never tried it). Given a standard (though not ideal, let it be real world) op-amp, it has 5 main inputs -- I+, I-, O, V+, V-. If no loops were formed, and V+ was connected to I+ and V- was connected to I-, would the output O always be the...

    Quinne-MCCluskey simplification

    Well, not that there are no PI's, but there are no essential PI's. An essential prime implicant is one that covers a min term that no other prime implicant covers. But in this problem, every min term is included in two different prime implicants (1 is in 1,3 and 1,5; 10 is in 10,11 and 10,14)...

    Quinne-MCCluskey simplification

    Answer About the problem. 1) Determine the minterms. If they are not given, this is best done in a truth table. We need to know all the min terms, because some of the combinations look hidden F=ABC' + ACD' + A'B'D + B'CD + A'C'D _ ABCD|F -------+- 0 0000|0 1 0001|1 A'B'D...

    Quinne-MCCluskey simplification

    Hey. My name is Matthew Howell, I'm living in Pensacola, FL. In a week I will have a bachelor's of computer engineering. I'm 22 :smile: I also have dial-up, so that is why my replies are so sparse. But we have time to work. Sorry I can't add more, but I am working out the problem and the...

    Quinne-MCCluskey simplification

    Are you sure you copied down the problem right? The solution you gave is a minimal one (check it by K-map).

    Quinne-MCCluskey simplification

    Almost right You cannot combine these two. The first term (00x1) does not depend on the variable C. The second term (0x01) does depend on the variable C. A similar argument can be made for the variable B. So, 0xx1 is not a Prime Implicant. For Quine McCluskey, you can only combine terms that...

    How did you get the PI of 0xx1?

    Why would a circuit have a zero ohm resistor (3 black bands) in it?

    Another Question I have another question on the same topic. Does anybody have any more analog (as opposed to digital -- like a switch -- or mechanical -- like PCB layer avoidance) ideas for the use of 0 ohm resistors? the reason why I ask is because they are sold with very high, very specified...
