The index for normal-mode radiations from a signal line was studied. Even if some digital IC have a same function, the radiation from a signal line changes with kinds and manufacturers of digital IC. In order to calculate this difference of the normal mode radiations, the output model of digital IC was consisted of a voltage source and an output resistor. The output resistance is calculated from output voltages of digital IC and an input impedance of a signal line in order to consider the switching characteristics of digital IC. The calculated values of the normal-mode radiations by using the output model of digital IC agreed very well with the measurement results. And the authors proposed the ratio of an open-circuit output voltage and an output resistance of digital IC as the index for the normal-mode radiation from a signal line. This ratio is valid as the index, because the normal-mode radiation is closely correlative with this index. And it was confirmed that the maximum value of the normal-mode radiation was able to be calculated by using this index.
