Testing using standard function generators for frequency response, pulse response is common. Oftentimes, certain nonlinear systems such as testing of saturable reactors, semiconductors of the p-n-p-n type as well as testing of avalanche conditions in power transistors need sharp rise and slow fall signals To this end, a PC based function generator where any kind of signal pattern such as the above, including wavelets could be realized with a very simple circuit, combined with a power OPAMP. Circuits of the above type could be tested using this set-up. The software is developed in Visual Basic.
