We calculated the radial synthetic model of receiver function consisting of the sedimentary layer, crust, and mantle (SCM). The models were computed using the program hrftn96 implemented in computer program in seismology (CPS). Synthetic receiver functions are generated using the following parameters: for sedimentary layers, Vp, Vs, and density are 1.8, 0.41 and 1.83 g/cm

respectively; for the crustal layer, the values are 6.10, 3.52 and 2.73 g/cm
3
with the depth of the Moho layer at 40 km; and for the mantle, the values are 8.15, 4.7 and 3.36 g/cm

. We varied sedimentary layer with the thickness of 0.0, 0.4, 0.5 and 1.0 km. We applied the Gaussian width parameter of 1.5 removing frequency content above 0.75 Hz. We designed the filter for the synthetic receiver function model in order to minimize reverberation effect due to the presence of sedimentary layer near the surface. To test the effectiveness of this filter, we adopted H-κ stacking method for this model to calculate the moho thickness before and after sediment removal.
