| Abstract: | This paper describes an auditory-evoked potential processing system composed mainly of an amplifier with an extralow noise, an overlapping processor, a programmable auditory stimulator and a recorder. It has multiple functions including detection and amplification, averaging overlap, cursor value determination and power spectrum analysis. The results can be displayed on a CRT or recorded by an X-Y recorder. The programmable auditory stimulator can be programmed to generate about 100 different kinds of stimulus, including the click, tone burst, spectrum wave, trapezoid wave, alternative pulse wave, half sinusoid cycle and white noise to meet the requirements of clinical application and fundamental medical research. Therefore, this system is of great use in the field of auditory neural physiology. |
