Complex spectral logic
Claudio Moraga · International Symposium on Multiple-Valued Logic · 1978
A spectral expansion of multiple-valued logical functions is studied. Chrestenson transforms and a mapping of logical functions into the unit circle in the complex plane are used. It is shown that a set of transformations in the function domain corresponds to permutations and/or complex scaling in the spectral domain. Spectral expansion of a function is unique and this is used to reduce complexity in multiple-valued logic design.
