ELE541 Old Exam Problem Quantization

  • What is the LSB of an ideal 8-bit ADC that has a full-scale input range of 0-5 V?

  • What is the expected RMS value of the quantization noise?
    • Answer
    VRMS = LSB/sqrt(12) = 5/255*sqrt(12) = 5.66 mV

    This problem is a lot like Exercise 6.5 page 166 of the text.
