Brain Activity Recording For CSIR NET
Electroencephalography (EEG) is a non-invasive technique used to record Brain activity recording For CSIR NET. EEG signals are typically recorded using electrodes placed on the scalp, which detect the electrical activity of the brain.
A researcher recorded an EEG signal with a sampling frequency of 100 Hz. The raw signal had an amplitude range of 10-100 ฮผV.

Question: If the EEG signal is analyzed using Fourier transform, what will be the frequency resolution (ฮf) of the power spectral density (PSD) plot?
ฮf = 1 / T, where T is the total time duration of the signal. Assuming a 10-second EEG recording,ฮf = 1 / 10 = 0.1 Hz.
