Hi,
Is it good Idea to design low pass filters (moving average , FIR filter, Kalman filter, Butterworth and Chebyshev filter) with same filter parameters (cut off frquancy, filter order etc.) for comparision purpose inorder to filter the higer frequancy noise?
For the selction of best filter to filter higher frequancy noise.

My preference would be an elliptic IIR filter for efficiency. See the documentation for ellip for details. For best results, begin with ellipord, and get the [z,p,k] output from ellip, then use second-order-section representation for stability with zp2sos. Use that result with filtfilt to do the actual filtering.
