Thank you for the reply Coen, "With active electrodes, the source impedance is transformed to less than 1 Ohm on the electrode, and no interference currents flow through the electrode-gel-skin interface." Can you recommend any journal articles that I can cite for this sentence? I assumed the article...

Following the above post, I found an article that would be interesting to the audience in this field: https://www.neuroregulation.org/article/view/14604 The article compares DC offset and impedance readings in electrode connection quality and concludes that DC offset is not a reliable measure of ele...

Hello Biosemi team, I wish to know if there are detailed reviews that I can read to properly understand the concept of offset as it applies to EEG acquisition. The questions that I have are as follows: 1. What is the definition of offset? ActiveTwo operation manual says it is the "running average of...
