The possibility of designing a tunable chemical oscillator is explored. In contrast to a normal oscillator which when subjected to external forcing exhibits the characteristic unimodal resonance curve, a tunable oscillator reveals a constant response curve. This persistence of resonant behavior for a wide interval of forcing frequencies is seeked both numerically and in an experimental electrochemical cell. Our results indicate that, although challenging, a tunable chemical oscillator can indeed be conceived.
