"Noise-Based Logic. Why Noise, Why not Sinusoidals?"
When noise dominates an information system, like in nano-electronic systems of the foreseeable future, a natural question occurs: can we perhaps utilize the noise as information carrier? Another question is: Can a deterministic logic scheme be constructed where the logic information is carried by noise, like in the brain? The answers to these questions are: yes, and noise-based logic. However a new question appears: Although noise-based logic shows potential advantages of reduced power dissipation and the ability of large-scale parallel operations, with low hardware and time complexity, the question still persist: is randomness really needed out of orthogonality? Can we just use deterministic signals such a sinusoidal signal system instead, with perhaps better characteristics? After introducing noise-based logic, we address this question.
