1. An electroencephalogram measuring apparatus comprising:

  • an electroencephalogram detection unit which detects electroencephalogram data;

    an electroencephalogram amplifying unit which amplifies the electroencephalogram data measured in the electroencephalogram detection unit;

    an A/D converting unit which converts the amplified electroencephalogram data from an analog signal to a digital signal;

    an electroencephalogram processing unit which, using the electroencephalogram data which is converted into a digital signal, outputs an output value for each frequency at each time interval for the ground state of an experimentee, and determines whether or not noise waves are combined with the electroencephalogram; and

    a display unit which displays the result of the electroencephalogram processing unit.
