PPT-Chapter 6 Errors, Error Detection, and Error Control

Introduction All transmitted signals will contain some rate of error gt0 Popular error control methods include Parity bits add a 1 or 0 to the end of each seven bits Longitudinal redundancy checking LRC. Maxino Member IEEE and Philip J Koopman Senior Member IEEE Abstract Embedded control networks commonly use checksums to detect data transmission errors However design decisions about which checksum to use are difficult because of a lack of informat A sensible approach to teaching usage and mechanics.
