Logic resonance is a method for enhancing the accuracy of logical operations through the response of a nonlinear system. The study of logical resonance began with logical stochastic resonance, followed by the introduction of logical vibrational resonance, logical chaotic resonance, and other related concepts. This chapter introduces the concept of logical system resonance. Given the central role of logical operations in technological advancement, improving their accuracy is of paramount importance. The goal of this chapter is to provide insights that can inspire the development of more efficient logical operations. In the order of their introduction, this chapter examines logical stochastic resonance, logical vibrational resonance, and logical system resonance.
