A IBM PC-based processing system for evoked potentials has been developed. The system includes: 1) preamplifier and preprocessing, 2) data acquisition (A/D converter), 3) programmable auditory stimulator, 4) IBM PC-based analysing and processing system. In this system, two methods of signal processing, overlapping averaging and adaptive averaging filter, have been used. The results have shown that this system has high performance and low cost.
