DC Sources Based on Operational Amplifiers

The results of an analysis of dc-source circuits based on operational amplifiers from the point of view of their internal resistance and the error in generating the output current are presented.     

Response Rate Choice for Reactivity Meters

Simulation has been used to estimate the error in reactivity measurement in relation to the response rate in an instrument which integrates the input signal or by a converter with a constant measurement time without integration.     

Errors of a Reactivity Simulator Based on a Digital-to-Analog Converter

Estimates are obtained of reactivity simulator errors when implemented on the basis of digital-to-analog converters as influenced by the number of bits and additive noise.     

Analysis of the Errors of a Reactivity Meter

Simulation is used to estimate the error of reactivity measurement as a function of the sampling rate, the ADC resolution, and the additive noise.     

The Basis of the Structure and Choice of the Parameters of a Simulator of a Pulsed Fission Chamber

The choice of such parameters of the generator as the resolving power and the number of digits of the code-interval converter is validated by analyzing the instrumental errors as it applied to the specific structure of a Poisson process generator.
