Technical And Digital Specifications Of The Polygraph - Rpsgt

Front 1

What is the maximum electrode Impedance recommended in the polygraph?

Back 1

The EEG impedance of 5 KΩ should be measured before and rechecked during the recording when the technician notes artifacts.
The 5 KΩ relates to measuring EEG and EOG electrode impedance.

Front 2

What is the desirable sampling rate in Hertz’s for the EEG, EOG, EMG, and the minimal sampling rate?

Back 2

The reason for the 500 desirable rate is the 500 resolutions helps to improve the look of spikes in the EEG and help improve the look of waveforms in the EEG.

Front 3

What is the Desirable Sampling Rate for the Airflow, Chest and Abdominal Belts and the Minimal Sampling Rate?

Back 3

Desirable rate is 100 Hz – Minimal rate – 25

Front 4

If you need to change the sampling rate and high frequency filter – the sampling rate should be how many times the high frequency filters?

Back 4

The sampling rate should be at least (3) times the high
frequency filters

Front 5

The recommended recorded filter settings for the low frequency filter for the EEG, EOG, ECG?

Back 5

0.03 Hz

Front 6

The recommended recorded The digital polygraph systems must have the following feature?

Back 6

A) Separate 50/60 Hz filter
B) Capability of Selecting sampling rate
C) A method of measuring individual impedances
against a reference
D) Identify whether sleep stage scoring was
preformed visually or computed by the system

Front 7

The recommended EEG derivations are?

Back 7

A) F4-M1
B) C4-M1
C) O2-M1
and back up
F3-M2
C3-M2
O1-M2

Front 8

The M1 and M2 in the Electrode derivation refers too

Back 8

Named after the Mastoid bone the Mastoid process.

Front 9

The correct placement of the EOG derivation - E1-M2 and/or E2-M1 is?

Back 9

E1-M2 is placed 1 cm below left outer canthus – E2-
M1 – is placed 1 cm above right outer canthus

Front 10

How many chin EMG’s are recommended and Describe in detail where one of the chin EMG’s should go?

Back 10

3 Chin EMG’s are recommended
