Standard deviations and trip rates were calculated for the period indication (voltage pro­portional to growth rate) for a system consisting of eight diode pumps satisfying Equations (2-1) and (2-2), and for which Tg = 2 seconds, T2 = 80 seconds, and R^Cj = RgCg = 2 seconds.

The standard deviations at various average counting rates are given In Table 2-6.

Then, using the largest стр listed in Table 2-6 (4. 8×10 nepers/sec), the average rate at which the period Indication exceeds the true growth rate (1/P)T by an amount (1/P)E is shown in Table 2-7.
