Hi all,

I have a very basic question about stride frequency. For cadence of 120 steps/min, stride frequency turns out to be 1 Hz. If this is the walking frequency then what do the higher harmonics (2Hz..3Hz upto 6Hz cut off frequency) of this frequency represent? Physical significance?

Another question is how do we decide order of Fourier fit for raw data smoothing (to remove noise)? Is it that, if 6 Hz is cut off frequency for my data, Fourier series upto 6 harmonics should be fit to filter the data?

Thanks in advance for your answers!
