Qualitative Analysis of Analog Circuits


Posted on Feb 6, 2014

At the beginning of a design process the designer has to verify which circuit structure is suitable for a given purpose. At this stage numerical and symbolic analysis are of little use. There are no numerical values for conventional simulation with programs like SPICE and a Symbolic Analysis would produce large symbolic expressions. No further app

roximation of these expressions can be performed due to the lack of numerical values. An experienced designer however, is able to analyze the behavior of an unknown circuit. The Qualitative Analysis reproduces this ability on computers by introducing qualitative states such as positive, zero, or negative. The applet is a graphical user interface to the QA Server. The QA Server performs the computations and runs on the same computer (, SUN Ultra450) as the WWW Server.
