I am building an EEG machine and intend to digitize the amplified analog signals for input into a
computer. I am considering using a 16 bit A/D for each channel. The question I have is: Is a 16
bit A/D overkill? Is 12 bits sufficient. What kind of voltage range am I liable to encounter on
the EEG electrodes? I intend to use isolation devices between the front-end
processor and the main computer.
Any advice would be appreciated.
