According to ACNS guidelines, Recording clinical EEG on Digital media requires
monitors to have___ Answer - Between 25 and 35 mm/second horizontal
scaling and a MINIMUM of 100 data points/second to accurately display EEG on
the monitor screen
, The filters creating a very narrow band pass that should rarely be used clinically
are
a. LF 5.0HZ and HF 70HZ
b. LF 5.0HZ and HF 15HZ
c. LF 0.1HZ and HF 70HZ

During the recording of cerebral activity, the calibration input voltage is
changed from 50uV to 100uV. What will be the result? Answer - no effect on
the activity being recorded
A spike is printed out on paper and measures 16mm peak to peak, the
sensitivity is 7uV/mm and a calibration signal of 50uV causes a deflection of
7.1mm. What is the voltage of the spike? Answer - 112uV
What input voltage is necessary to give a calibration deflection between 5 and
10 mm if the sensitivity is 30uV/mm? Answer - 200uV

data, should be at least ___ times the highest high frequency filter setting.
Answer - three

10 seconds per display screen to 20 seconds per display screen, the frequency
of the activity will be___ Answer - 10 Hz
Guidelines for recording digital EEG are written by___ Answer - The American
Clinical Neurophysiology Society (ACNS)
