Abstract

We investigate the designing of multiple-input and single-output (MISO) logic gates using a periodically driven double-well Duffing oscillator system. Our research focuses on the existence of OR and AND logic gate properties in the output of a single double-well Duffing oscillator with multiple inputs under the influence of external periodic forcing and bias. Through our investigation, we demonstrate that the logic gate can be switched between OR and AND by adjusting the bias value. Our approach successfully scales the number of logical inputs for both the gates up to ten and even more. Additionally, we verify that the logical output of this nonlinear system maintains robustness against noise.
