I have got three signals, acc_x, acc_y, acc_z. I need to compose them in order to compute the magnitude of the acc. I would like to ask the following question:
what is better opt1 or opt2? or opt3?:
**opt1**: first apply a filter to reduce the noise to each single signal and then compute the magnitude or, **opt2**: first compute the magnitude and then apply a filter to the composed to reduce the noise? **opt3**: Any other good suggestion?
Any of your suggestion would be very appreciated.
Thank you in advance.
Best Regards, Carlo
