| Abstract: | This paper presents two programs implemented on a microcomputer for analog-to-digital (A-to-D) conversion of neurophysiological signals. The first program, TIMET, sets flexible pulse trains for the timing of the A-to-D conversions, executed by the second program, ADC8. TIMET contains options for a continuous or a triggered pulse train with variable onset delay. ADC8 allows sampling up to 30 kHz for one channel and 9 kHz for the maximum of 7 channels, with about 8 microseconds lag between channels. The digitized data are displayed with interactive gain control from keyboard input, and selected sweeps can be stored on disk files. |
