Auditory Brainstem Response, ABR (or Brainstem Auditory Evoked Potentials, BAEP) is a human body physiology parameter at microvolt level. First, we use the TMS320F2812 of TI company, making the signal through D/A transform and high accuracy operational amplifier, and produce the masking white noises, as well as the Tone Burst to be the stimulus. Then, the evoked EEG will be amplified and filtered. At the same time, we use the A/D of TMS320F2812 to collect and process the signals, and get the digital BAEP.
