Along with the new device, O/S, and Ovi Store, the new Nokia Qt SDK brings the popular Qt Creator IDE from the desktop and embedded worlds to mobile developers, enabling them to build native apps for Symbian^3 devices like the N8.

    Correction:

    You need to sample it at twice the maximum cut-off frequency of the
    frequency spectrum of the signal.

  • Vijay ….Re. CRC codes ….

    You need the best book on Error Control Coding ever written

    ‘Error Control Coding An Introduction’ ISBN 0-13-284126-6 (1991 soft cover edition)
    by Dr Peter Sweeney of Surrey University, Guildford, Surrey, UK.

    Looks like there was a reprint in 2002, if you can’t get it anywhere else, I suspect the Surrey University bookshop will have copies.

    The easiest, nicest explaination of FEC under the sun and as one of his old students I have to say a very nce guy.

    Cheers, E.T.

  • I didn’t hear the 16kHz sound, but I do hear that sound that TVs, moniters, etc. make when you turn them on.
