Modified AMI code — Modified AMI codes are Alternate Mark Inversion (AMI) line codes in which bipolar violations may be deliberately inserted to maintain system synchronization. There are several types of modified AMI codes, used in various T carrier and E carrier… … Wikipedia
B3ZS — is an abbreviation for bipolar with three zero substitution, a T carrier line code in which bipolar violations are deliberately inserted if the stream of user data contains a string of 3 or more consecutive zeros. B3ZS is used to ensure a… … Wikipedia
Hybrid ternary code — The hybrid (H ) ternary line code operates on a hybrid principle that combines the binary non return to zero level (NRZ L) and the polar return to zero (RZ) codes and thus it is called H ternary. The H ternary code has three levels for signal… … Wikipedia
Unipolar encoding — is a line code. A positive voltage represents a binary 1, and zero volts indicates a binary 0.Its drawbacks are that it is not self clocking and it has a significant DC component component, which can be halved by using return to zero, where the… … Wikipedia
