FIRST  ORDER SENSITIVITY ANALYSIS OF EQUIVALENTLY TRANSFORMED SIGNALFLOW GRAPH
Irina Asenova The determination of the sensitivity of the circuit functions is a task whose solution is important in the synthesis of various types and use electrical and electronic devices. Sensitivity analysis is especially needed in the design of frequency selective devices.
In the paper relationship between sensitivity of transfer functions of signal flowgraphs and similar sensitivity of the equivalent signalflow graph transformation is defined. These transformations do not affect the transfer function of the circuit, but change first and higherorder sensitivity on the same transfer function. Some cases of loops without delay elimination are considered and a relationship between the firstorder sensitivity transfer function with respect to the transmission coefficients before and after transformation the equivalent of signal flow graph is obtained. анализ на чувствителността предавателни функции еквивалентни трансформации на сигнални графиsensitivity analysis transfer functions equivalent transformations.Irina Asenova BIBLIOGRAPHY [1] R.E.
