cancellation effect

cancellation effect

A condition in which positive and negative charges or same frequencies of positive and negative polarities nullify each other. The cancellation effect may result from unintentional interference in a line or circuit, or it may be purposely created. For example, noise cancellation systems generate frequencies with opposite polarities to the undesirable signals in order to eliminate them.
