Oscillations in the first-order digital recursive filters with representations of numbers in additional code with round-off
Jurij Brjuhanov · Izvestiya VUZ Applied Nonlinear Dynamics · 2004
Processes in low-pass and high-pass filters with ап arbitrary number of quantization levels are investigated. Numbers are represented in additional code and the results of adding are rounded. Adder have the characteristic with saturation. Using dot mappings method, the autonomous regime and oscillations under constant external influence are considered. Expressions for calculating the most probable operating modes are obtained.
