<P>PROBLEM TO BE SOLVED: To provide an electrocardiogram measurement system improved in detection accuracy of an electrocardiographic signal. <P>SOLUTION: In the electrocardiogram measurement system 1, an electrocardiographic signal generating unit 10 has a correction circuit 12a between a sensor circuit 11a and a differential amplifier 13, and a correction circuit 12b between a sensor circuit 11b and the differential amplifier 13. Accordingly, detection signals output from the sensor circuits 11a and 11b, are corrected by the correction circuits 12a and 12b, and a difference between the detection signals are made by the differential amplifier 13. Thus, the SN ratio being the ratio of signal to noise is increased before and after correction by the correction circuits 12a and 12b, unlike a conventional art configured to simultaneously amplify a detection signal and a noise superposed on the detection signal, and further the detection accuracy of the electrocardiographic signal is increased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
