B- 30 Hz to 3,000 Hz
C- 100 Hz to 1,000 Hz
D- .5 Hz to 200 Hz - ANSWER✔✔ B- 30 Hz to 3,000 Hz
To accurately represent the amplitude of an EP waveform, a match must be made
between the
A- dwell time and sampling rate
B- signal size and the vertical capacity of the digitizer
C- high‐frequency noise and smoothing operation of the instrument
D- horizontal resolution and signal size - ANSWER✔✔ B- signal size and the
vertical capacity of the digitizer
, In selecting the horizontal parameters of analysis, the
A- sampling rate should be the equivalent of the highest frequency in the signal
B- analysis period should be at least twice the Nyquist frequency
C- sampling rate should be at least two times greater than the highest frequency
in the signal
D- analysis period should approach the Nyquist frequency - ANSWER✔✔ C-
sampling rate should be at least two times greater than the highest frequency in
the signal
The assumption that responses of excessive amplitude are likely to contain
artifact forms the basis for
A- digital filtering
B- artifact rejection
C- dwell time
D- digital averaging - ANSWER✔✔ B- artifact rejection
In a differential amplifier used for intraoperative monitoring, the common mode
rejection of in phase signals is typically
