In the practical A/D converters, if the first transition may not occur

1.	In the practical A/D converters, if the first transition may not occur at exactly + 1/2 LSB, then such kind of error is known as ____________(a) Scale-factor error(b) Offset error(c) Linearity error(d) All of the mentionedThe question was asked in an interview for job.My question is from Quantization and Coding topic in section Sampling and Reconstruction of Signals of Digital Signal Processing
Answer» The correct ANSWER is (b) Offset error Explanation: We NOTE that practical A/D converters MAY have offset error (the first TRANSITION may not occur at exactly + 1/2 LSB).
