Abstract:
1. A signal transmission circuit, comprising: a first transmission path having a first impedance; a terminating resistor having a predetermined resistance and electrically connected on one end only to a second transmission path and on another end only to ground; and said second transmission path having a second impedance, one end of which is connected to the first transmission path, other end of which is connected to the terminating resistor, the second impedance being higher than both of the first impedance and the predetermined resistance, wherein the second transmission path is formed by using a substrate wiring of a specified length such that it creates a wiring delay so as to provide a positive reflection between the first and second transmission paths and a negative reflection between the second transmission path and the terminating resistor, and wherein a signal is received at a connection portion of the first transmission path and the second transmission path.
