I am recording 6 channels from a force transducer, but there is a 50 Hz noise I want to remove. I was considering to use a simple solution as iirnotch, but I don't have this function on my Matlab R2015a. How can I create a filter (filtfilt and fir1?) to eliminate this 50 Hz without a signal processing toolbox?
Thank you

Actually, I don't have the DSP toolbox and I have an old version of the Signal Processing toolbox.
