Abstract
A filter for suppressing noise surges and noise frequencies in ac power lines to an audio video load includes at least one noise suppression circuit. The noise suppression circuit in turn includes first and second inductors coupled to respective power lines in series with the load. A capacitor is coupled between the power lines at the input of the first inductor and the output of the second inductor. With this arrangement, the capacitor suppresses noise surges in the power line, while being protected by the second inductor from being damaged by the surges. Also, the filter suppresses two noise frequencies using only the single capacitor. If desired, additional noise suppression circuits can be provided, with each noise suppression circuit suppressing two noise frequencies using only a single capacitor.
