Answer» Right option is (b) EEG To explain: EEG electrodes give high SKIN contact impedance as COMPARED to ECG electrodes. GOOD electrode impedance should be generally below 5 kilohms. Impedance between a pair of electrodes must also be BALANCED or the difference between them should be less than 2 kilohms.
