Abstract: To disclose a biomedical signal processor with a simple configuration and a minimum space capable of confirming an operating condition and a signal collection state of the biomedical signal processor such as an electrocardiograph. As an example of the biomedical signal processor according to the present invention, a Holter electrocardiograph supplies biomedical signals to a light-emitting element (LED) 30 and applies a bias supply voltage from a power supply section 80 to the LED 30.
