Active filter design software AktivFilter 3.3

AktivFilter 3.3

The usual problem

You are an electronics engineer, you have to develop an electronic device, and you need an active filter circuit which fulfills your specification. After the test of your built circuit, you observe that the frequency response deviates from your specification. So, you try to adjust the circuit, you measure the frequency response, and you repeat this very often. This matching can be a quite time-consuming process.

Our solution: AktivFilter 3.3

AktivFilter 3.3 design software is able to design active filters, which are tuned on the operational amplifier and on the standard series (E12, E24, E48, E96, or E192) of resistors and capacitors. This tuning works so fine that a manual matching of the designed filter circuit becomes unnecessary. AktivFilter 3.3 can design active bandpass filters, highpass filters, lowpass filters and notch filters. For many applications AktivFilter enables you to use inexpensive (slow) opamp types instead of expensive (fast) opamps. AktivFilter supports many special high-quality audio opamps, which are used in audio electronics - in consumer products, studio equipment and high-end equipment.

AktivFilter can create filters with the characteristics Bessel, Butterworth and Chebychev. Additionally, you can specify an individual characteristic by setting the parameters pole quality Q and the normalized pole frequency for each stage of your active filter. This can be a useful feature, e.g. if you want to develop a special active crossover network for loudspeakers.

While AktivFilter 3.3 is able to co-ordinate filter designs on opamp types, it is important, that the program supports all ordinary opamp types. Here is a list of all supported opamps:
