<!--StartFragment-->The Su–Schrieffer–Heeger (SSH) model composed of an electrical circuit is known to behave as an electrical bandpass filter. In our previous presentation, the variation of eigenfrequencies, which is a key feature toward the mass production of bandpass filters, was numerically calculated by varying component values of SSH circuits. In this presentation, we will discuss an experimentally obtained variation of eigenfrequencies in one-dimensional SSH circuits.
