Claim 22:
23. A method of reconstructing a digital signal having a rising edge and a falling edge, the method comprising:
producing a first transient response corresponding to the rising edge of the digital signal, the digital signal conducting through a first conductive trace on a first circuit board and the first transient response being produced on a second conductive trace on a second circuit board, the first conductive trace and the second conductive trace being in a contactless coupling that is based on proximity of the first conductive trace and the second conductive trace, the contactless coupling enabling the second conductive trace to produce the first transient response;
generating a logic high level in response to the first transient response;
producing a second transient response corresponding to the falling edge of the digital signal, the second transient response being produced on the second conductive trace based on the contactless coupling; and
generating a logic low level in response to the second transient response, thereby reconstructing at least part of the digital signal.
