All of the following may be helpful in identifying 60-Hz artifact
EXCEPT:
increasing the LFF from 0.3 hz a. applying and removing the AC (line) filter.
to 1.0 hz b. decreasing time base to count the frequency.
c. decreasing the HFF from 70 Hz to 35 Hz.
d. increasing the LFF from 0.3 Hz to 1.0 Hz.
One of the MOST important roles of the recording technologist is
to:
document any changes in a. score sleep stages prior to applying treatment
recording parameters b. document any changes in recording parameters
c. record interpretation of patient comments and actions
d. assure patient completes the pre-sleep questionnaire
increasing sampling rate What would increase the resolution of EEG spikes and
improve definition of the waveforms?
a. applying 50/60 Hz filter
b. using a 100 uV input voltage
why; Advanced digital
c. increasing sensitivity
acquisition systems
d. increasing sampling rate
samples continuous signals
at a fixed rate, called a
sampling rate. The
Nyquist
theorem states that a digital
copy of a
signal can be completely
reconstructed from
samples made at a
sampling rate faster than
twice the bandwidth of

the highest frequency of
the original data.
Sampling at a higher rate
facilitates more accurate
reconstruction of the signal.
EEG spikes, such as those
seen in epileptiform
activity, require a high
sampling rate to
reconstruct the signal,
enhance resolution and
improve the definition of
the waveform.
