    What is basic difference between C and C# for embedded systems?

    C $ C# i dont use or even know C#, but C# is somekind more related to java than to c++. It needs .net or other alternativas (mono as open source etc). Unless you get mono or .net working in your embedded system if i'm not wrong you can't use C# ( ? )

    need matlab codes in DSP???? view in

    i don't agree about the passwords. It is not the way to work int this board. Why do you want it this way?

    Using FPGA to control ADC and DAC

    fpga cds adc 1. any ram will be useful, but remember you need interface, if you use ddr, you'll need a ddr controller etc. the modules are available but that needs more space. Maybe you can use internal memory (some fpgas have it) but not to store 25 seconds of 24 bits sampled audio. 2...

    Converting ORCAD schematic to PCAD schematic

    orcad pcad netlist right, just use only the netlist, export it to the format needed and do forward/backward ECO if needed. we use orcad for schematics (compatibility is an issue) and our designers use mentor graphics for pcb. converting from one software to another from time to time...

    Suggestions on VHDL books for practical learning of the language

    VHDL Book ? this couple are good: Circuit designt with VHDL, Pedroni, MIT Press or VHDL programming by example, Perry, McGraw Hill search around forum, several topics about this thread already discussed :)

    Double sided PC boards unsoldering parts?

    un soldering temperature for pc board why not using solder wick for the easy ones? for ic the best is air-hot station, not available you can try: - (destructive), just cut the pins and unsolder pins individual, or - apply solder in all the pins (shortcut all of them) and apply heat in all...

    Looking for resources to learn about probability and random processes

    probability Peebles it's simple and easy. Probably a good one for the first steps but maybe it should have more examples. But i liked more Papoulis.

    Why PSK is better than FSK?

    hmm, maybe: 1. Analog: FM is easier to modulate/demodulate than PM. 2. Digital: BFSK needs 2 times bit energy more than BPSK to get the same probability of error. (i.e points in constellation are nearer).

    Looking for references to learn H.264

    Re: H.264 learning this second one is still free ?, it said something about € and user/password to download it. Maybe i've done something wrong, or maybe we are unlucky and it isn't free no more.

    What should/need I to know when I start a PCB design?

    p-cad 2001 torrent once you now how to make a pcb i suggest reading this book: ( "High-Speed Digital Design: A Handbook of Black Magic" ) Its a must for every pcb designer.

    What are advantages and disadvantage of using schematics over HDL coding?

    Re: Schematic V/S HDL is there any vhdl to sch "block modules" translator ?. I mean , separating vhdl in modules an just click and "watch" somekind a sch of modules and interconexion between them ? (just as informative sch, not needed architecture of the modules).

    How can I convert Eagle layout(*.brd) to OrCad (*.brd) ?

    anyway i dont think there is a direct way to do it.

    Do you use auto-route for PCB layout packages?

    Re: Do you auto-route? high speed, analog, power-ground, coupled lines, ... manual rest of pcb just let the autorouter try it.
