Is it possible? I haven't found anything about it on the internet.
I found a logic analyzer here, which is marketed as having the capability to monitor analog signals too: "One useful feature of your Saleae Logic Analyzer is its ability to measure analog signals (from 0 to 5 V). As such, it can function as an oscilloscope with up to 8 channels (for the Logic 8 and Logic Pro 8) or 16 channels (for the Logic Pro 16)." (https://support.saleae.com/tutorials/example-projects/how-to-measure-analog-signals)
Could that function as a 16 channel EEG recorder?
As I know, a human EEG electrode would pick up a signal peaking at around 0.1 V... would it be a problem?
