WebWith a modern microprocessor based ratemeter one technique for measuring field strength with detectors (e.g., Geiger–Müller tubes) with a recovery time is Time-To-Count. In this technique, the detector is armed at the same time a counter is started. When a strike occurs, the counter is stopped. WebMay 22, 2015 · Expressions for the expectation value of the number of counts obtained during a fixed measuring time can be derived from the first moment of the N -fold time-interval distribution. For input pulses forming a Poisson process with rate ρ, the expected output rate R for a counter with non-extendable dead time τn is [ 1, 5 ]

WebIn transitive terms the difference between count and rate is that count is to consider something an example of something while rate is to berate, scold. In obsolete terms the difference between count and rate is that count is an object of interest or account; value; estimation while rate is ratification; approval. WebHowever, users should note that this method for calculating the MOE and SE for aggregated count data is an approximation, and caution is warranted because this method does not consider the correlation or covariance between the component estimates.
