    Hello all,

    I'm trying to answer a question on my assignment but I've forgotten the answer. Google is no help, so I'm looking to be pushed in the right direction.

    Question is:
    Name a device that coverts one wave form (Such as digital) to another on a computer network by modulation.

    Many thanks,

    Wasley

    Hi,

    Be more precise. What is 'digital waveform' ? Waveforms are not digital, unless represented in digital form (PCM for example).
    Also, I've got no idea what 'modulation' as a method has to do with computer networks.

    What you're looking for may be a "CODEC" or "DSP".


    Cheers,

    Modems. They convert digital computer data to analog sound waves and then demodulate the carrier signals to decode the transmitted information.

    You are here.
    What you need is a modulator/demodulator. The modem (modulator/demodulator) is indeed the simplest example.

    But in reality every device that trasmits/receives data over analogue lines (hardwired or wireless) is such a device. Bluetooth, WiFi, NIC they all use this technology. Because data is transmitted in analogue form and then interpreted and processed in digital form.
