Error Detection and Correction Transmission of data through a noisy medium inevitably introduces errors through interference by changing one or more bits. There are two types of errors‚ in single bit errors‚ a 0 may be turned into a 1 or vice versa. In real world conditions‚ most interference introduce burst errors where two or more bits are switched from a 0 to a 1 and vice versa. Types of Errors 1. Single-Bit Error – a single bit is switched from a 0 to a 1 or a 1 to a 0 2. Burst Error
