The electrical signals that an EEG (Electroencephalography) record can be differentiated by the frequency of each signal. Brain activity is measured between a frequency of 0 Hz and 30 Hz. This activity is often differentiated into four-significant brainwave frequency bands: Delta, Theta, Alpha, and Beta: 1. Delta (0-4 Hz): Samples in this frequency range are associated with restfulness and deep sleep. 2. Theta (5-7 Hz): Samples taken in this range indicate meditative states and sometimes drowsiness. 3. Alpha (8-13 Hz): Samples in this range are related to a relaxed alertness and sometimes meditative states as well. 4. Beta (14-30 Hz): These waves indicate alertness, mental engagement, and conscious processing. Furthermore, beta waves have been referred to as an indication of focus or attention.

Question
The electrical signals that an EEG (Electroencephalography) record can be differentiated by the frequency of each signal. Brain activity is measured between a frequency of 0 Hz and 30 Hz. This activity is often differentiated into four-significant brainwave frequency bands: Delta, Theta, Alpha, and Beta: 1. Delta (0-4 Hz): Samples in this frequency range are associated with restfulness and deep sleep. 2. Theta (5-7 Hz): Samples taken in this range indicate meditative states and sometimes drowsiness. 3. Alpha (8 - 13 Hz): Samples in this range are related to a relaxed alertness and sometimes meditative states as well. 4. Beta (14-30 Hz): These waves indicate alertness, mental engagement, and conscious processing. Furthermore, beta waves have been referred to as an indication of focus or attention. If we want to study the relationship between brain activity signals and decision of swinging or not at a baseball pitch by novice vs expert players we would need to design a filter that will let us study EEG signals in the Beta category. Note: Assume that we are receiving signals with frequencies of 0 to 30Hz from the instrumentation.
