USING THE MATHCAD SOFTWARE PACKAGE IN THE PROBLEMS OF SENSITIVITY ANALYSIS OF SECONDARY PARAMETERS OF ELECTRONIC CIRCUITS

It is proposed to use the MathCAD software package to analyze the sensitivity of the secondary cir-cuit parameters. For example, a transistor amplifier circuit is proposed. It is proposed to determine the tolerances for the primary parameters of the circuit based on the sensitivity analysis of the sec-ondary parameters. It is proposed to use the potentials of the circuit nodes as secondary parameters when conducting direct current analysis. The constructed relative sensitivity matrices make it possible to determine the tolerances for the nominal values of the circuit elements
