Hardware Butterworth Filter

 

Due to the success we were having with using the software Butterworth Filter, Tony decided to design a hardware filter. This filter is used mainly on noisy or cluttered signals like the data received from the Capacitor Sensor. The only downside of using a hardware filter is it has a fixed filter setting and can’t be easily changed. This filter works well, but once a recording is made, no practical adjustment of the filtered data can be done. NASA and similar entities, have used software post-processing to extract useful data from noisy signals, for decades. It is the most flexible approach.

Just below, is a recording of the output of the Hardware Butterworth Filter and the Raw Capacitor sensor signal output from the circuit above. The Hardware Butterworth filter closely matches the Software Butterworth Filter as can be seen in the images further below.

Software Butterworth Filter


By example here are the results with the software Butterworth Filter using the same raw data but with different filter settings.

0.0005 Setting, this setting is similar to what we are getting with the hardware filter
