The ideal phase-detector characteristic is analyzed mathematically for an estimation of the phase difference between two stochastic input signals. High signal-to-noise conditions are assumed in order to linearize the system with respect to the noise. The effects of nonlinearity on the signal are analyzed using a series expansion and low-pass filtering on the receiver output. The mean-square error of the detector is calculated for some typical parameters. Author
