What would increase the resolution of EEG spikes and improve
definition of the waveforms?
a. applying 50/60 Hz filter
b. using a 100 uV input voltage
c. increasing sensitivity
d. increasing sampling rate - Correct Answer - increasing sampling rate
Advanced digital acquisition systems samples continuous signals at a
fixed rate, called a sampling rate. The Nyquist theorem states that a
digital copy of a signal can be completely reconstructed from samples
made at a sampling rate faster than twice the bandwidth of the highest
frequency of the original data. Sampling at a higher rate facilitates more
accurate reconstruction of the signal. EEG spikes, such as those seen in
epileptiform activity, require a high sampling rate to reconstruct the
signal, enhance resolution and improve the definition of the waveform.
