A 5-bit analog-to-digital converter (ADC) has a voltage range of 0 to 4 V and a digitization uncertainty of ±1 LSB. What is the maximum uncertainty if the digitization is for a 4 V signal? What is the maximum uncertainty for a 17-bit ADC, and for 34-bit? If this ADC has a conversion time of 21s, then what is the highest frequency that can be precisely digitized while satisfying the Nyquist criterion?
