ADC
What magnitude do neural signals measure before amplification?
what is microvolts or millivolts
The Fourier transform changes which domains?
What is time domain to frequency domain
How can EEG be used to monitor someone reporting a lack of deep sleep at night? What steps must be taken to extract that data? How might one locate an overactive brain region contributing to their condition?
1. Amplification & digitization
2. Conversion of time to frequency components
3. Bandpass filtering for low frequency/high amplitude delta waves
4. Common average reference/Laplacian filtering for highly localized activity
T/F: Signal amplification typically occurs as a distinct process from digitization
What is False
What is the type of distortion that occurs when sampling rates are less than the Nyquist criterion?
What is aliasing
