Various studies of Standard Model parameters involve measuring the properties of a coherent admixture of 
and 
states. A typical example is the determination of the Unitarity Triangle angle 
in the decays 
, 
. A model-independent approach to perform this measurement is proposed that has superior statistical sensitivity than the well-established method involving binning of the decay phase space. The technique employs Fourier analysis of the complex phase difference between and decay amplitudes and can easily be generalised to other similar measurements, such as studies of charm mixing or determination of the angle 
from 
decays.
