Texas Instruments: Numb3 Rs: Error Correction

Curated by ACT

Based off of the hit television show NUMB3RS, this lesson has students explore Hamming Codes, an error correction technique used on slightly unreadable or damaged compact discs. Students see how the Hamming Codes allow a CD player to "fill in" missing or confusing pieces of data. As an extension, students then make observations on a UPC Code ("Bar" Code), which also include an error-detecting technique.
