WebNamely, the output signal is amplified at a frequency that is absent from the input. Thus, a ghost frequency response can be triggered by either a noise intensity (ghost-stochastic resonance) or a high-frequency force (ghost-vibrational resonance). - Coherence Resonance. LONELY NOISE PHENOMENON WebApr 29, 2024 · Abstract. In the former works of Yang et al., they put forward two vibrational resonance (VR) methods in fractional Duffing oscillators to amplify the weak harmonic character signal with arbitrary high-frequency. Moreover, the aperiodic character signal is also a common signal form in practical engineering. For the “fast-changing” aperiodic …
