1. An electronic device comprising:
- a printed circuit board (PCB) including at least one conducting wire;
a first integrated circuit (IC) placed on the printed circuit board and including a transmit pin electrically connected to the at least one conducting wire; and
a second IC placed on the printed circuit board and including a receive pin electrically connected to the at least one conducting wire,wherein the first IC is configured to;
transmit a specified signal having a first voltage through the transmit pin;
change an internal impedance of the first IC based on a reflected signal of the specified signal at a first time point; and
transmit information about an impedance of the at least one wire to the second IC; and
wherein the second IC is configured to change an internal impedance of the second IC based at least on the information about the impedance of the at least one wire.
