Maximum error

  1. Dec 10, 2008 #1
    Hello all,
    If i use 4-bit A-D converter to convert an analog voltage of say 8 volts, then can some one tell me what's the maximum possible error that i can expect in my result and how to predict it before performing experiment.
    Thanks.

    Moved to homework help forums.

    What are your thoughts? What is the granularity of a typical *linear* 4-bit ADC? What if you used a non-linear ADC? Why would you use one versus the other?

    And beyond the ideal ADC resolution, what other factors might contribute to a larger practical error budget?
