A unit of resistance is symbolized by
A- A
B- ohms
C- E
D- micro - answer B- ohms
The capacity to resolve amplitudes of 256 discrete steps would
require an 8 bit A to D converter. This can be represented by:
A- 8
B- 8/256
C- 256
D- 2^8 - answer D- 2^8
What is the minimum required bandpass for an EP system?
A- 1 - 1000 Hz
B- 0.1 ‐ 5000 Hz
C- 30 ‐ 1500 Hz
D- 1 Hz - 20 KHz - answer B- 0.1 ‐ 5000 Hz
The gain of an amplifier, set to give an output signal of 1 volt for an
input signal of 10 microV, is
A- 100,000
,B- 10,000
C- 100
D- 1,000 - answer A- 100,000
A 100 mS epoch is recorded with a 10 mS post ‐ stimulus triggering.
Which of the following best describes the resulting sweep?
A- A 100 mS sweep starting 10 mS after the stimulus
B- A 90 mS sweep starting 10 mS after the stimulus
C- A 100 mS sweep starting 10 mS prior to the stimulus
D- A 110 mS sweep starting 10 mS prior to the stimulus - answer A-
A 100 mS sweep starting 10 mS after the stimulus
SSEP recordings typically require a bandpass of
A- 1000 Hz to 5,000 Hz
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
A- 100:1
B- 5:1
C- 10,000:1
D- 500:1 - answer C- 10,000:1
A differential amplifier records
A- the second half of the two inputs
B- only the first two inputs
C- the second half of the two inputs
D- the difference between the two inputs - answer D- the
difference between the two inputs
The Nyquist frequency is:
A- equal to the sampling rate
B- 1/3 the highest frequency
