Phasors of nominal frequency signals

Consider a constant input signal x( t) at the nominal frequency of the power system f 0, which is sampled at a sampling frequency Nf 0. The sampling angle θ is equal to 2π/ N, and the phasor estimation is performed using Eqs. (1.25–1.27).
$$x (t)= X_m \cos(2\uppi f_0 t +\phi)$$
