Digital Fuzzy Operations Using Multi-Valued Fredkin Gates
Hafiz Md. Hasan Babu · 2022
Multi-valued Fredkin gates (MVFGs) are reversible gates and these gates can be considered as modified version of the better-known reversible Fredkin gate. Reversible logic gates are circuits that have the same number of inputs and outputs and have one-to-one and onto mapping between vectors of inputs and outputs. Moreover, multi-valued Fredkin gates have been shown to be a suitable choice as a basic building block for binary and different alternative logics for example multi-valued logic and threshold logic. The introduced circuit is composed of MVFG which are reversible gates. Reversible logic gates are circuits that have the same number of inputs and outputs and have one-to-one and onto mapping between vectors of inputs and outputs; thus, the vector of input states can be always reconstructed from the vectors of output states. The reversible logic finds its application in many fields such as quantum and optical computing, low power design, nanotechnology, etc.
