Abstract: This paper reports and discusses the processing response dependence on a spin-wave reservoir chip, a natural computing device, to present one of the important steps to design a spin-wave reservoir computing hardware. As an example, we deal with a sinusoidal-square wave distinction task, where signals with a certain duration switch to each other at random. Observation of the transient response provides us with information useful for determining chip size and other parameters. Accumulation of this type of investigations will elucidate how we should design a spin-wave reservoir chip.
