Number of averages | Estimated noise (µV) | Factor re single sweep | sqrt(N) |
---|
N = 7 | 3.7 | 2.5 | 2.6 |
N = 13 | 2.6 | 3.5 | 3.6 |
N = 25 | 1.9 | 4.8 | 5.0 |
- The first column states the number of different stimulation amplitudes used for averaging. The second column shows the estimated noise. The third column shows the decrease in noise compared to the recording without any averaging. The forth column shows the expected reduction of uncorrelated noise due to the number of averages
