The location of periodic noises in phase of AC power wave reveals to be specific according to the noise kinds which can be generally classified into modulation and baseband types in DLC. The former noise type has constant noise phase which is originated from switching mode power supplies and the latter normally caused from thyristor circuit of low switching frequency is compared to be more dispersive than the other.
