Hey guys, Basically, I have been doing some testing with regards to tactile vibrations (I know that isn't very electrical) and using a HET have developed several amplitude plots in the time domain. I've been sampling at 5000Hz and I want to remove the noise from my signals to leave me with a clean (hopefully!) sine wave. I then want to use this wave, along with another amplitude-time graph (basically a side profile of the sample used for testing) in order to produce a transfer function for the human finger. I undersrtand that Matlab can do this for me but I can't figure out how! Sorry if i've posted this in the wrong area, can anyone help!?
