Which of the following component is generally designed to have a very high value of input impedance to take care of high electrode impedance?(a) Montages(b) Filters(c) Electrodes(d) PreamplifiersI have been asked this question in my homework.This intriguing question comes from Multi-Patient Telemetry topic in division Biomedical Telemetry of Biomedical Instrumentation

Answer»

The CORRECT option is (c) Electrodes

For explanation: EEG preamplifiers are GENERALLY designed to have a very HIGH value of input impedance to take care of high ELECTRODE impedance. 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.
