Signal averaging is commonly used in the recording of ERPs because it reduces the magnitude of
A) large signals.
B) sensory evoked potentials.
C) random signals.
D) the P300.
E) far-field potentials.

Question

Quizplus · Accepted Answer

Signal averaging reduces random noise in the recorded signal by averaging the responses to the same stimulus, thus reducing the magnitude of random signals. It does not specifically target large signals, sensory evoked potentials, the P300, or far-field potentials.
