A real-time brain wave measuring apparatus and method for measuring the brain wave of a subject and transmitting the measured brain wave via a serial port to a brain wave analyzing computer in real time, is provided. The brain wave measuring apparatus includes a brain wave sensor for sensing brain wave signals of multiple channels at predetermined portions of the subject's scalp using a plurality of electrodes, an interface and a serial port connector connected to the interface via a cable and connected to the serial port. The interface includes an amplifier for amplifying the amplitudes of the brain wave signals of multiple channels, the brain wave signals which are sensed by the brain wave sensor; an analog-to-digital converter for sampling and digitizing the amplified brain wave signals of multiple channels; an encoder for coding a digital value calculated by the analog-to-digital converter of each channel in real time; and a computer interface for transmitting the brain wave signals which are coded by the encoder to the serial port. Accordingly, brain wave signals of multiple channels are sensed and transmitted through the serial port to the brain wave analyzing computer in real time even if the brain wave analyzing computer is not equipped with special hardware for processing brain waves therewithin.
