4. Average of signals
In order to calculate the average, the sum of the signals 1 to 5 is added and divided by 5. A copy of this signal is also made and filtered.
- Signal 6 is the average of signals 1...5 (black signal)
- Signal 7 is the average (red signal), filtered twice; from start to end of protocol and from end to start; it is a non-causal filter of 50ms!
