  The set up of matched filters for the detection of gravitational waves from
in-spiraling compact binaries is usually carried out using the restricted
post-Newtonian approximation: the filter phase is modelled including
post-Newtonian corrections, whereas the amplitude is retained at the Newtonian
order. Here we investigate the effects of the introduction of post-Newtonian
corrections also to the amplitude and we discuss some of the implications for
signal detection and parameter estimation.
