1.	In the practical A/D converters, if the difference between the values at which the first transition and the last transition occur is not equal to FS – 2LSB, then such error is known as _________(a) Scale-factor error(b) Offset error(c) Linearity error(d) All of the mentionedI have been asked this question in an interview.My doubt is from Quantization and Coding topic in section Sampling and Reconstruction of Signals of Digital Signal Processing
Answer» CORRECT answer is (a) Scale-factor ERROR Easy explanation: We note that PRACTICAL A/D converters scale-factor (or gain) error (the difference between the values at which the first TRANSITION and the last transition OCCUR is not equal to FS — 2LSB).
