Noise-based logic (NBL) [1] [2] is a new class of multivalued deterministic logic schemes where the logic values and bits are represented by different realizations of a stochastic process. The scheme is inspired by the brain where the neural signals are stochastic spike sequences. The logic values are represented by multi-dimensional vectors and their superpositions, where the orthogonal basis vectors are independent noises. By the proper combination (products or set-theoretical products) of basis-noises, which are called noise-bit, a logic hyperspace can be constructed with D(N) = 2N number of dimensions, where N is the number of noise-bits. Thus N noise-bits in a single wire correspond to a system of 2N classical bits that can express 22N different logic values.
