Noise measurement uncertainty calculator

***DRAFT***

This calculator estimates the uncertainty to a given confidence level of measurement of noise of a given bandwidth for a given integration time due to the measurement sampling process (alone).

... be warned it is slow for large integration times and bandwidths unless you use the "Fast" option.

Integration time (s)
Bandwidth (Hz)
Confidence level (%)
Faster approximation
Uncertainty (dB)

The "Faster approximation" uses an inverse square law extrapolation for cases where Bandwidth*IntegrationTime is greater than 1000 and confidence level is greater than 50%, otherwise the slower method is used.
