Abstract(in English)	For performance evaluation of linear block codes, we can evaluate by union bounds based on the weight distribution. This approach is applicable for convolutional codes by a terminating. Therefore, if the input-output weight distribution can be derived, the error performance of concatenated codes can be evaluated. In this paper, first, the results of input-output weight-enumerating function of terminated convolutional codes are shown. Next, for terminated 2- and 4-state convolutional codes, it is shown that the input-output weight distribution can be expressed as function of the number of information symbol. Furthermore, the application for serial concatenated convolutional codes is considered.
