Abstract
This article provides an elementary overview of quaternary i.e., ℤ4 codes and sequences and assumes very little background. It begins with a discussion of binary m-sequences and uses the excellent autocorrelation properties of these sequences to motivate the study of finite fields. This is followed by a discussion of the family of Gold sequences.
