Biosignal measurement device, electroencephalograph, and control method |
| abstract |
A biosignal measurement device includes: a first chopper amplifier circuit that receives a biosignal detected by a measurement electrode contacting a living body, and is chopper-controlled based on a first control signal; and a controller that selectively performs one of a biosignal measurement mode operation for outputting the first control signal having a first frequency to the first chopper amplifier circuit and a test mode operation for outputting the first control signal having a different frequency from the first frequency to the first chopper amplifier circuit. |
