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 flow-graphs and similar sensitivity of the equivalent signal-flow graph transformation is defined. These transformations do not affect the transfer function of the circuit, but change first and higher-order sensitivity on the same transfer function. Some cases of loops without delay elimination are considered and a relationship between the first-order sensitivity transfer function with respect to the transmission coefficients before and after transformation the equivalent of signal flow graph is obtained.
