Provided is an electronic device to monitor a user’s biological measurements, where a sensor is configured to acquire a first signal from a user, and a diagnostic processor is configured to pre-process the first signal to generate a second signal, segment the second signal to form signal segments, determine at least one event location for each of the signal segments, match adjacent signal segments for feature alignment, and provide a third signal using results of the feature alignment.一種電子裝置，用以監控使用者的生物特徵測量，其中，感測器經配置以自使用者取得第一訊號，以及診斷處理器經配置以對第一訊號進行預處理，產生第二訊號，將第二訊號分割以形成數個訊號段，針對各訊號段，判定至少一個事件位置，將相鄰的訊號段匹配以進行特徵對準，以及利用特徵對準的結果，提供第三訊號。
