Description
Summary:Nowadays, there are many of publications dealing with the design of frequency filters. Only a limited number of articles is addressed the issue of unbalanced resistive termination in the filters design. The paper deals with a design two-port network operating between a resistive generator with internal resistance and a resistive load. A design of the filters with unbalanced termination resistors according to available Butterworth standard tables of normalized filter coefficients is not so easy. In this case was created a program which can solve a design problem. For calculation of the coefficients and the Butterworth-type filter design, the script in MathCAD 14 program was created that performs automatic calculation of component values.
