We investigate the effect of deterministic input signals on a quasiperiodically driven Murali–Lakshmanan–Chua (QPDMLC) circuit, which exhibits strange nonchaotic attractors (SNAs). We show that if one uses two-square waves in an aperiodic manner as an input to a QPDMLC circuit, the response of the circuit canproduce a logical output, controlled by such forcing. We also demonstrate that one of the variables of the circuit exhibits one logic element, while the other variable shows its complementary logic operation. It is further shown that these logical behaviors persist even for an experimental noise floor. Thus we confirm that SNA is an efficient tool for computation as in the case of the quasiperiodically driven Duffing oscillator.
