I'm currently involved in attempting to make a crude pedometer.
It has come to the stage where i am reading in signals and plotting them on Excel to analyse...
The data is quite noisy due to step bounce back and various other reasons. I am taking in a single acceleration vector and was trying to use the following DSP filter design tool that i found through the york cs department to design a Butterworth low-pass filter:

It may be that I am inputting the wrong values for the necessary fields but at the same time I am having trouble translating the Ansi "C" code to Java!
Would anyone be able to lend a helping hand?
