Biological signal measuring device, electroencephalograph, and control method |
| abstract |
The biological signal measuring device (10b) is a first chopper amplifier circuit (52a) into which a biological signal detected by a measuring electrode (51a) in contact with a living body is input, and is based on a first control signal (CS1). The operation of the first chopper amplifier circuit (52a) controlled by the chopper, the operation of the biological signal measurement mode for outputting the first control signal (CS1) of the first frequency to the first chopper amplifier circuit (52a), and the first frequency. It is provided with a control unit (60) that selectively executes a test mode operation that outputs first control signals (CS1) of different frequencies to the first chopper amplifier circuit (52a). |
