ADC Resolution

Hi,

     I would like to know how "oversampling" of an ADC channel increases its resolution.

Regards,

Naveen.

    Over sample and average multiple samples to get more accuracy.

    Suppose a signal required sampling at 1KHz; to increase 2 bits more accuracy, sample at 16KHz, sum every 16 samples and right shift 2 times (/4).
