When we analyze signal data, we use many techniques such as fast fourier transform method, low pass filtering, and so on. However, if noise signals of big amplitude are measured with the data signal, then the information in the measured signal may not be analyzable. The mechanical filter can be used to filter out signals of big amplitude. In this paper, we studied characteristics of some materials for the mechanical filter using accelerometer. We described general transfer function form of mechanical filter and measured transfer function of some materials for the filter.
