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.

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. Switched capacitor filters are good for steep roll-off and these are available in Butterworth filters.

MAC (multiplier/accumulator) suitable for digital filter realization. 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. Developed tools for filter design are also available in MatLab (Jackson 1995. That means that your signal amplitude will be flat throughout the frequency range. 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). There is a filter design toolbox that is pretty useful. The magnitude response of the filter is displayed in the Filter Analysis area after the coefficients are computed.MATLAB is a pretty good place to start for filter simulation and design. After setting the design specifications, click the Design Filter button at the bottom of the GUI to design the filter. Wpass and Wstop, in the Magnitude Specifications area are positive weights, one per band, used during optimization in the FIR Equiripple filter. With thoughtful features that make mundane tasks easy, and an intuitive interface that won’t interrupt your flow, you’ll do amazing things with Sketch. Enter 0.2 for wpass and 0.5 for wstop in the Frequency Specifications area.Ħ.

Select Normalized (0 to 1) in the Units pull down menu in the Frequency Specifications area.ĥ. Increasing the value creates a filter which more closely approximates an ideal equiripple filter, but more time is required as the computation increases. The FIR Equiripple filter has a Density Factor option which controls the density of the frequency grid. Select Specify order in the Filter Order area and enter 30.ģ.

In general, when you change the Response Type or Design Method, the filter parameters and Filter Display region update automatically.Ģ. Select Lowpass from the dropdown menu under Response Type and Equiripple under FIR Design Method. We will use an FIR Equiripple filter with these specifications:ġ. We will design a low pass filter that passes all frequencies less than or equal to 20% of the Nyquist frequency (half the sampling frequency) and attenuates frequencies greater than or equal to 50% of the Nyquist frequency. You can right-click or click the What's This? button to get information on the different parts of the tool. The tool includes Context-sensitive help. Other panels can be displayed in the lower half by using the sidebar buttons. Starting at the front page for the tool, I selected Lowpass, then allowed the tool to use all default values by selecting.

This morning I was able to get results, but this afternoon it seems the tool is now broken. It controls what is displayed in the other two upper regions. I've been using the TI Filter Design Tool for my current project for a few months now. NET Framework assemblies (.dll) describing the methods and data for a mainframe TP. The Design Panel, in the lower half is where you define your filter specifications. TI Designer creates TI objects stored as. The lower half of the GUI is the interactive portion of Filter Designer. The Filter Display region, in the upper right, displays various filter responses, such as, magnitude response, group delay and filter coefficients. It also provides access to the Filter manager for working with multiple filters. The Current Filter Information region, in the upper left, displays filter properties, namely the filter structure, order, number of sections used and whether the filter is stable or not. The upper half of the GUI displays information on filter specifications and responses for the current filter.
