Short summary
Recently, nonlinear amplifiers based on the Andronov–Hopf bifurcation have become a focus of attention in modeling of the mammalian hearing organ. We present a flexible framework implemented on a DSP to analyze various bifurcation based amplifiers to get deeper insights in their nonlinear input-output behavior. A comparison shows the Neimark–Sacker amplifier remarkably outperforms the Andronov–Hopf amplifier regarding the CPU usage.
