The Fisher Files

In this part, we pose an interesting question, work out the characteristic impedence of a transmission line and learn how to terminate a line.

In this podcast, we talk about using the Poisson distribution in fits where bins have fewer than ten counts. As an example, I’ve generated 100 data sets for the muon lifetime experiment and fit each one using Gaussion and Poisson statistics. The Gaussian fit has a mean fit value of 2.02 microsconds, while the Poisson has 2.29 microseconds. These are for the same data sets generated with a 2.2 microsecond muon lifetime.
