blocked is a ___ Answer - Filter
A combination of electronic components designed to increase the power,
voltage or current of a signal___ Answer - Amplifier
A small fluctuating output recorded by the EEG instrument even when there is
no input signal is called___ Answer - noise
The EEG amplifier is designed so that when input 1 is more negative than input
2, the deflection will be___ Answer - Upward
Common Mode Rejection is___ Answer - The characteristic of an amplifier that
rejects external interference

a. 0.5Hz
b. 5.0Hz
c. 10Hz
d. 0.1Hz Answer - d. 0.1 Hz
Time constant is defined as the time required___ Answer - For the deflection
to fall(decay) to 37% of the peak deflection
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

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

of the activity will be___ Answer - 10 Hz
Guidelines for recording digital EEG are written by___ Answer - The American
Clinical Neurophysiology Society (ACNS)
