We have developed a modified version of the classical multiple filtering technique for the frequency-time analysis and we apply it to two-station phase velocity estimation. Two of the profiles crossing the older Moldanubian and Tepla-Barrandian units are characterized by higher velocities of 3.8 km/s in the upper crust while for the Saxothuringian unit we find the velocity slightly lower, around 3.6 km/s at the same depths. We obtain an indication of a shear wave low velocity zone above Moho in the Moldanubian and Tepla-Barrandian units. The area of the Eger Rift (Tepla-Barrandian-Saxothuringian unit contact) is significantly different from all other three units.
