Electrical communication system for a bicycle

摘要

A bicycle signal processing device 12 includes a first bicycle signal processing element that generates a first signal having a first impedance, an external output terminal having an exposed output contact surface, and an impedance converting circuit 150 coupled between the first bicycle signal processing element and the external output terminal 170 for converting the first signal to a second signal having a second impedance at the external output terminal 170. <IMAGE>
