About us

SoftwareDidaktik presents products which should make easier the job in the electrical engineering and electronics development.

Stefan Bayer is a certified engineer of electrical engineering and a professional software developer. The modelling of oscillators, filters, and transistor amplifiers belongs to his experiences, in particular for the use in computer-aided design (CAD) of these circuits. He has built the software AktivFilter for the design of active filters: lowpass filters, highpass filters, bandpass filters and notch filters. AktivFilter is able to tune the components values of the active filter to the operational amplifier type and to the standard values of the components. In this way a later adjusting of the built up circuit is not needed anymore and in many designs inexpensive standard opamp types can be used instead of expensive special opamp types. According to our information, AktivFilter is worldwide the only available program with these properties.
