V. L. Golovkin, A. S. Shaposhnikov, A. K. Shashurin · 1984
Mathematical model of the influence of the additive interference of random type on the accuracy of the digital automatic bridge measuring compensator with pulse feeding and digit-by-digit balancing is given. Interference is described by a harmonic series with deterministic or random /in reference to the geginning of the bridge balancing/ phase spectrum. This model is realized as a computer programm. Main inner cycle of the program is repeated for each phase of modelling digit-by-digit bridge balancing in the presence of interference. External cycle of the program provides for statistic modelling. Program allows for finding statistical characteristics of the errors of digital output readings of the compensator due to interference. Model may be used for EMC calculations for the use of the compensator with other instruments containing interference sources.
