We review the properties of Galactic binaries containing two
compact objects, as derived by means of population synthesis. Using
this information we calculate the gravitational wave signal of these
binaries. At frequencies below 
mHz the double white dwarf
population forms an unresolved background for the low-frequency
gravitational wave detector LISA. Above this limit some few thousand
double white dwarfs and few tens of binaries containing neutron
stars will be resolved. Of the resolved double white dwarfs
~500 have a total mass above the Chandrasekhar limit. About
~95 of these have a measurable frequency change allowing a
determination of their chirp mass. We discuss the properties of the
resolved systems.
