Two inexpensive electronic circuits for analog display of multichannel EEG signals.
Two electronic circuits useful for high-resolution EEG recording systems are described. The first is an analog display driver that formats large numbers of EEG signals for display in a variety of modes on a standard CRT display. The second is an analog demultiplexer circuit that reconstitutes large numbers of analog EEG signals from multiplexed D/A outputs. Each provides a readily expandable, high-resolution EEG display that can easily provide real-time or faster performance and that is much less expensive than computer-based digital display systems with comparable capabilities.
