RESUMEN
The ambulatory EEG recorder designed in this paper can continuously record 24-hour EEG signals on 18 channels. C8051F020, a kind of mixed-signal ISP FLASH MCU, controls all the functions such as sampling, storage and many others. The 12-bit ADC in C8051F020 samples the EEG signal amplified by the preamplifier. At the same time, the EEG signal of every channel can be selected through the keyboard to be displayed on LCD so that the working status can be detected. After the system is ready, the signals sampled during 24 hours are stored into the CompactFlash card as FAT16 files.
