    Building a PCI Analog I/O card

    Thanks, Do you happen to have a basic PCI card that I could learn from, I simply want a comprehensive example, because I'm not sure where to begin. Thanks again

    Building a PCI Analog I/O card

    Hello all, Basically, I want to use my computer as an electronics station (Oscilloscope, Multimeter, Function generator...). Could anyone tell me how to build a PCI card, maybe even get me started on such a data aqcuisition card? I've searched the web and I found lots of sites on doing things...

    Can I use HFSS 9.1 for optics simulations?

    Well, Specifically, my simulation has a cylindrical symmetry, but not a 'z' symmetry. I guess I can take only one quarter of the fiber and simulate it, but I'm not shure how to do that, and I didn't find an option like that in HFSS.

    Can I use HFSS 9.1 for optics simulations?

    Hi, I have an optic fiber (something a little different in shape, but the same for the sake of discussion). Basically I want to know the energy at one end of the fiber as a function of the energy I put in at the other end. I want to know this as a function of the wavelength that I put in...

    What excitation in HFSS I need for a passage of light ?

    Excitations in HFSS Hello, I'm trying to simulate a passage of light via an optical fiber and I'm not sure which excitation to assign. I've tried a waveport but it says that the fiber cant be made of glass because it is dialectric. I though that maybe Incident wave would work, but it doesnt...

    Can I use HFSS 9.1 for optics simulations?

    Hmmm... Thats what I need to do. I left it all night and it wasn't enogh. Are there any other programs especially for optics that I can use? Could I arrange a "Super Computer" with enogh RAM and enough CPU power. Can you approximate how much RAM I need, considering that I can leave the...

    How to add a new material to HFSS 9.1?

    Adding a new material Hello, I want to add a new material to HFSS 9.1. How is it done? What are the parameters needed for the program? Thank you.

    changing frequency ranges

    Hello, I wish to "take" the frequency range 50Hz-3kHz (speech) and "move" it to the frequency range (for example) 10kHz-13kHz. After that, I would like to return the signal to its original frequency range. How do you call such circuits, and does anyone have a link to a site with these...

    Can I use HFSS 9.1 for optics simulations?

    Hello, I want to simulate the passage of Infrared light (~10^14Hz) via a fiber optic wave guide (0.8mm in diameter). I was woundering if HFSS can give me an accurate solution for such parameters. Thank you.
