The program filter pro is an active filter design program from Texas. Overview Software Details Documentation Design Resources Training Support. The Internet has some new EM simulation software, known as Flex-PDE for 2D and. Most importantly - ensure you comply with the Nyquist criteria and that you are sampling at at least twice the highest frequency, in practice, this means sample at four - 10 times your highest frequency, to allow for filter roll off well below your ADC resolution level at the Nyquist rate. Real-time edge Software enables real-time applications built on the i. This shifts cost and complexity from analog components to software and processing requirements. These do need a single pole before and after them to remove an aliasing due to the clock signal of the switching which occurs anywhere from 50 - 100 times greater than your cut-off.Īlternatively use a simple single pole RC filter (active or passive) and feed into a higher speed ADC and then you can use digital signal processing on an embedded platform or PC to perform decimation and analysis. Material effects such as dispersion, volumetric absorption, volume scattering, and color filtering can also be included. Switched capacitor filters are good for steep roll-off and these are available in Butterworth filters. Luckily for hams and other experimenters, there. Stay away from implementing a Sallen-Key topology active filter, it is very difficult to get all the components to be matched and maintain good accuracy, try doing a Monte Carlo simulation on a Sallen-Key circuit to get a better understanding. There are several filter design software packages ranging from simple calculators to sophisticated CAD programs.

That means that your signal amplitude will be flat throughout the frequency range. I find the work flow is generally faster and more enjoyable. I'm also getting into using a lot of free software for my work.

I honestly don't know much about how to design them by hand, I've been using the Genesys tool. However it does come at a cost.įor sensor applications Butterworth filters are generally better as they have a maximum flat passband (at the expense of phase response and roll off). I'm finding myself needing to do a fair bit of analog filter design. There is a filter design toolbox that is pretty useful. MATLAB is a pretty good place to start for filter simulation and design.
