PROBLEM TO BE SOLVED: To improve accuracy of analysis.SOLUTION: A biological signal analyzer comprises: acquisition means for acquiring a biological signal from a biological signal measurement device for measuring the biological signal of a measurement object； trigger information acquisition means for acquiring trigger information indicating a time when stimulation occurred, from a stimulator for applying the stimulation to the measurement object； and signal processing means for processing the biological signal. The signal processing means calculates the biological information on the measurement object based on the biological signal, then leaves only trigger information at a time when it is determined that the biological signal of the measurement object occurs from the calculated biological information, deletes other trigger information, and, based on residual trigger information, uses an addition average waveform obtained by addition average processing to the biological signals which occur in synchronization with the stimulation, for the signal processing.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】解析の精度を向上させる。【解決手段】測定対象の生体信号を測定する生体信号測定装置から前記生体信号を取得する取得手段と、前記測定対象に対して刺激を付与する刺激装置から前記刺激が発生した時刻を示すトリガ情報を取得するトリガ情報取得手段と、前記生体信号を処理する信号処理手段と、を備え、前記信号処理手段は、前記生体信号に基づいて測定対象の生体情報を算出し、算出した生体情報から測定対象の生体信号が発生すると判断される時刻のトリガ情報のみを残し、他のトリガ情報を削除し、残ったトリガ情報に基づいて、前記刺激に同期して発生する前記生体信号を加算平均処理した加算平均波形を信号処理に用いる。【選択図】図３
