Abstract :
The investigation of accuracy for methods of defining of the phase for delayed harmonic signals with white noises in digital systems. The method intended for digital processing of signals with use of electronic computing devices is offered, its comparison with a correlation method is carried out. The method is able to uses for digital commutation systems. Comparison with correlation methods is performed. The paper includes recommendations on the choices of Nyquist frequency and signal to noise ratio.
