study of Quantization of continuous-amplitude, discrete-time analog signals. 
What is the term used to describe the range of an A/D converter for bipolar signals?
What is the term used to describe the range of an A/D converter for uni-polar signals?
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 ____________
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 _________
In the practical A/D converters, if the differences between transition values are not all equal or uniformly changing, then such error is known as?
