I have an excel file containing 2 columns of data. Time and Encoder Raw data. From there I would like to smooth out the data (with lowpass filter FIR if possible) without using signal processing toolbox like sgolay? I have tried using sgolayfilt as a test to see if it works and now I want to do without it. How do I go about this?

Thank you very much and kind regards

Not sure what your edit was, but you still forgot to attach the Excel workbook.
