I have the signal of vibration data, the fft plot of which shows multiple harmonics/frequencies. I am trying to filter out all except particular frequency harmonics, that i need for further processing. I have no idea of any filtering tools in matlab. Can someone refer me material i can use to write a code for the above purpose.
Hi Shravan, If you have a signal processing tool box, you can use the FDA tool(filter design and analysis tool) to design a band bass filter by specifying the pass band frequency. (type fdatool to command window). You can export the filter ciefficients to workspace later.
