  We derived a post-Newtonian (PN) inspiral only gravitational waveform for
unequal mass, spinning black hole binaries. Towards the end of the inspiral the
larger spin dominates over the orbital angular momentum (while the smaller spin
is negligible), hence the name Spin-Dominated Waveforms (SDW). Such systems are
common sources for future gravitational wave detectors and during the inspiral
the largest amplitude waves are emitted exactly in its last part. The SDW
waveforms emerge as a double expansion in the PN parameter and the ratio of the
orbital angular momentum to the dominant spin.
