Sažetak
The method presented here is intended for high accuracy measurement of all parameters of a low frequency (method was tested up to 500 Hz) sine wave. It is relatively simple and, because of its exceptional resistivity to the random errors of samples, applicable for use similarly in calibration laboratories and less demanding measurements. Uncertainty of 10 ppm for all parameters of a sine wave is an ordinary result obtainable with this method, so it can be used for calibration of almost all AC calibrators and insurance of traceability. The only notable disadvantage of this method is relatively long duration of sampling (about 45 s), what makes this method suitable only for measurement of signals with time-invariant parameters.
