Basic stuff

  1. Dec 11, 2005 #1
    Hi...
    I have just started reading about digital signal processing and I am a bit confused. I was wondering if you guys could help me... with probably too easy stuff.
    So... in order to convert an analogue electrical waveform into a digital wave, there are 3 steps: anti aliasing filtering, sampling and quantization...
    What exactly happens to the waveform during each stage?
    Do you know any sites where I can find any graphs that exemplify this process?


    Thank you!!!

    I'll be forever indebted!:)

    Filter-remove frequencies you might not be interested in
    Sample-input the voltage of the waveform to your circuit (A to D converter)
    Quantization-Code the input voltage into a digital bit representation
