“From Edison to Viterbi”
Communications and storage are very similar fields. In the first, information is transmitted from “here to there” and in the second, information is transmitted from “then to now.” The techniques used in one are relevant to the other and recently the two fields are merging. In this talk we will follow the progress of audio storage from Edison to MP3 players. The talk will include live demonstrations of original Edison phonographs and a discussion of Edison’s career and some fundamental mistakes he made that caused him to lose the market. The talk will conclude with a discussion
of how Viterbi detection played a key role in the evolution of audio recording.
