______________ is typical frequency range of standard EEG machines.(a)

1.	______________ is typical frequency range of standard EEG machines.(a) 70 to 140 Hz(b) 0.1 to 70 Hz(c) 0.05 to 0.1 Hz(d) 0.025 to 0.05 HzI had been asked this question in an online interview.I need to ask this question from Multi-Patient Telemetry topic in division Biomedical Telemetry of Biomedical Instrumentation
Answer» The correct option is (b) 0.1 to 70 Hz For explanation I would say: The TYPICAL frequency RANGE of standard EEG MACHINES is from 0.1 Hz to 70 Hz, THOUGH newer machines allow the detection and filtering of frequencies up to several HUNDRED Hertz. This may be of importance in some intracranial recordings.
