Instrumentation Questions And Answers
With Verified Solutions Already
Passed!!!
Question: What is the advantage of gold over other materials (eg. Stainless steel)
for

recording electrodes? - ANSWER✔✔ Longer time constant


Question: The slope of a hicut filter function which describes the decrease in filter
output with

increasing frequency above the cutoff is called: - ANSWER✔✔ The rolloff


Question: In order to display a negative peak at the electrode upward on the
screen it must be

plugged into the: - ANSWER✔✔ Negative input


Question: If your background noise is 5 uV, what will be the amplitude of the
noise after 100

averages? - ANSWER✔✔ 0. 5 uV


Question: A 60 Hz notch filter should not be used for evoked potential recording
because of: - ANSWER✔✔ The ringing artifact that comes from distortion of the
stimulus artifact


Question: A differential amplifier with a Gain of 1000 will amplify an input voltage
of 1uV by: - ANSWER✔✔ 1000

, Question: You see a periodic sinusoidal noise waveform in your 100 mS SSEP trace
that
shows 6 repeating cycles across the sweep. What is the frequency of this noise? -
ANSWER✔✔ 60 Hz


Question: Aliasing is caused by: - ANSWER✔✔ Sampling below the Nyquist
frequency


Question: If the bin width of your system is 20 uS, then the highest frequency
signal that can

be resolved is: - ANSWER✔✔ 25 KHz


Question: What is the bin width of a system that has a sampling rate of 100, 000
Hz? - ANSWER✔✔ 10 uS


Question: Spinal cord evoked potentials are best recorded using a low frequency
filter setting
of 100 Hz. This setting is preferred because relative to cortical SSEPs, spinal cord
potenitals

are: - ANSWER✔✔ Of relatively short duration


Question: What can you say about a system trying to resolve a 40 µS sine wave
with a

sampling rate of 40 kHz? - ANSWER✔✔ Aliasing will occur
