Question

Consider an N-bits ADC (Analog to Digital Converter) whose analog input varies from 0 to Vmax, then which of the following is not true?

(a) The least significant bit correspond to a change of Vmax/2^N -1 in the analog signal

(b) The resolution of the ADC is Vmax/2^N -1

(c) The maximum error in the conversion (or quantization error) is Vmax/2(2^N -1)

(d) None of the mentioned

The question was posed to me by my school principal while I was bunking the class.
