      Theoretically possible, this is called Synthesis process, mostly this is dealt by Signal processing engineers. Refer this presentation (https://drive.google.com/file/d/0Bw1VlHh5X_tTNkJnZ2NPSnNfMjQ/view) for the brief over view. There is no ready-made procedure available for this either in Ansys Mechanical or MAPDL, though one can write a APDL macro for the math, but it becomes involved. However; Ansys nCode Design Life product can do this, attached PSD to Time_nCode Worked Example.pdf give you an idea.
