Abstract
A device for transmitting a pulse signal via a metallic line to a receiver end at which equalization is applied to the received pulse signal. The device includes a waveform adjustment unit which adjusts a pulse width in accordance with differences between characteristics of the metallic line and characteristics that are assumed for the equalization at the receiver end. The device further includes a transmission driver unit which transmits a pulse having the adjusted pulse width to the metallic line.
Claims9
A device for transmitting a pulse signal via a metallic line to a receiver end at which equalization is applied to the received pulse signal, comprising:
- a waveform adjustment unit which adjusts a pulse width in accordance with differences between characteristics of the metallic line and characteristics that are assumed for the equalization at the receiver end;
- and
- a transmission driver unit which transmits a pulse having the adjusted pulse width to the metallic line.
A device for transmitting a pulse signal via a metallic line to a receiver end, at which equalization based on assumed characteristics of the metallic line is applied, comprising:
- a waveform adjustment unit which adjusts a pulse width such as to compensate for differences between characteristics of the metallic line and the assumed characteristics;
- and
- a transmission driver unit which transmits a pulse having the adjusted pulse width to the metallic line.
A device for transmitting a pulse signal to a metallic line, wherein equalization is applied at a receiver end of the metallic line, comprising:
- a waveform adjustment unit which adjusts a pulse width;
- and
- a transmission driver unit which transmits a pulse having the adjusted pulse width to the metallic line, wherein the adjusted pulse width is such that a pulse obtained at the receiver end by applying the equalization to the pulse having the adjusted pulse width and having passed through the metallic line has a predetermined pulse width.
