  1. I've made a spice netlist of a circuit I am designing. The input to the circuit is an AC signal --> v1 1 0 dc 0 sin(0 34 60). Well I can do a transient analysis on this easily. But I also want to see what happens at the output as I vary the frequency. Unfortunately using .AC simply doesnt work. I suspect that I defined my signal source incorrectly to be used with .AC. Please help. Thanks.
  2. Hi MNA, I still dont have access to the folder. Thank you for posting the individual links :) But a few of the files have been removed by rapid share.
  3. Hi Prasarian :) and welcome to eLAB.
  4. You do realize that its a linux only program right? You gotta compile the source code.
  5. Sadly I havent been using OrCAD that much (especially its PCB design suite). When I want to design a PCB, I make the circuit in multisim and export the file to ultiboard. Ultiboard is pretty good IMO, partly because I've only used 2 PCB design suites :)
  6. Robot kits. yeah, I want :)
  7. Its now asking me for a password to access your folder...
  8. Great link EDA_Fan. I've booked marked it. Thanks for sharing!
  9. Hello Bassanova, I dont believe that multisim is used extensively in industry. For such purposes I believe they use OrCAD. You can request trial versions from: http://www.cadence.com/orcad/ OrCAD has something called PSIPCE, you design your circuits in orcad capture and simulate them with PSPICE. I prefer orcad to multisim because it provides more in depth analysis technique. But of course with increased functionality, comes complexity. I use the original spice and make all my circuits by using netlists. It takes extra time, but it is well spent.

  11. I will be getting my bachelors in computer engineering technology in about 1.5 yrs.
  12. Welcome to the forums poluroud20.
  13. Thats for uploading Ante. Great Stuff! :) http://www.electronics-lab.com/forum/index.php?topic=8942.0
  14. Ante, Do post all of them here. It would be great reference for myself and other elab users who are new to PLC.
  15. Hey all, I'm not familiar with PLCs. I only have experience working with the BASIC Stamp microcontroller. Are there any good reads for a newbie like myself? --thank you.
  16. This here is a very useful website: http://ai-depot.com/
  17. Sorry I have a life ;D Forums are a great plave to hang out and meet people with similar interests. I'm active on forums when I can.
  18. What calculator are you using, maybe the TI89? If so, the format is as follows: lcm(number1,number2)
  19. Happy Birthday mixos!! [move] :) :) :) :) :) :) :) :) :) :) :) :) :) :)[/move]
  20. You're welcome. Mouser sells LEDs in large quantities for cheap. Now you just have to figure out which type you want ;D
  21. Hey all, I've found a applet for circuits simulations. This isnt your everyday circuit simulator. With this one you can build your own circuits and simulate, but when the simulation starts, it shows how the current and voltage interact in the circuit. It also has the ability to show voltage, current, power, etc across components. There is also a huge library pre-built ciruits for you to learn from. I know that some teachers would kill to have this to help learning easier. http://www.falstad.com/circuit/ More applets can be found at my site in the links section. http://linuxfreak87.googlepages.com/ Regards, slackjack.
  22. Hi nickagian, Check out Mouser Electronics www.mouser.com and radio shack www.radioshack.com Mayb if you are looking for something in particular it may help us get better e-shops.
  23. Hey all, I'm curious. How can ohms law be dervied. The only way I can do it is by experiments. How do we arrive at V = IR without any experiments. Thats all ;D --thank you.
  24. Hi claudiorfernandes :) Welcome to the forums. Hope you will be an active member here.
