    Analog-to-Digital Conversion

     

    Microphones always create analog voice as the camera creates the analog videos that is called the analog data.

     

    For transmitting analog data into digital signal form we need the conversion from analog to digital.

     

     

    The data which is in the form of waves is analog data whereas the digital data is in scattered form.

     

     

    For conversion analog wave into digital data we do Pulse Code Modulation (PCM)

     

     

    PCM is one of the most commonly used method to convert analog data into digital form. It involves three steps:

    • Sampling
    • Quantization
    • Encoding.
