The Ideal Waveform. In public power distribution networks the ideal undistorted AC electrical signal has a typical frequency of 50Hz or 60Hz depending on the country or region.. Due to the method of generation, the signal alternates between proportionally equal, positive and negative values resulting in a pure sinusoidal waveform..
