The crucial link between continuous representations of information, such as music, and discrete representations of information, such as sequences of numbers, is provided by a mathematical discipline called sampling theory. The basic Shannon sampling theorem, for example, shows that if a music signal is bandlimited to 20KHz, …
WebbThe theorem is often called the Shannon Sampling Theorem, after UM alumnus Claude Shannon who published it in his pioneering 1948 paper on the theory of communications, which among other things made the sampling theorem widely known to engineers. The earliest versions of the theorem go back to 1847. 6.
