reversal? Answer: circumferential bipolar montage
◉ When using the average reference, if a spike-and-wave focus
appears at C3, the abnormality would be best enhanced by Answer:
excluding C3 and surrounding electrodes from reference
,◉ which of the following montages would best display the
amplitude of a left temporal spike Answer: left temporal to the
contralateral ear
◉ when attempting to minimize relentless muscle artifact on a
recording, the tech should be aware that lowering the high filter

assigned a numeric value Answer: sampling rate
◉ Digital EEG montages are reformatted by using Answer: system
reference
◉ Input impedance should be Answer: very high
◉ Low sampling rate may cause fast frequencies to appear slower:
