Multichannel data acquisition system for recording the acoustic brainstem response.
A system has been developed to sample and average multi-channel ABR data. All channels are sampled simultaneously. The simple design incorporates one sample-and-hold amplifier and one analog-to-digital converter in each channel. For sampling of 13 channels or less, sampling interval must exceed 36 microseconds for full 10-bit resolution. For sampling more than 13 channels, data transfer to the host computer limits minimum sampling interval to 20 + (1.2 X N) microsecond, where N is the number of channels sampled.
