Simulink - how to use a table look up to change the signal amplitude and phase of a signal

I want to apply a distortion to my signal based on its power level, which I am computing by the mean-square block. I then want to use this number (in dBs) to look up a distortion factor from my table-lookup and apply it to signal amplitude. I want to do the same to signal phase. So I have something like the following as my table look up.

Pin(dBs) Pout(dB) PhaseShift(Degrees) 0 -.5 5 -1 -.75 4 -3 -2 1

etc. I am having a hard time figuring out how to use the 2D Table look up block to do this. Any help will be most appreciated. Does the Table look-up automatically do interpolation? If yes, what type? Charan Langton
