Abstract
Various aspects of the present disclosure are directed to detecting crossings such as zero crossings that can pose problems to circuit operation. In accordance with an example embodiment, two or more circuits are implemented for detecting signal crossings of an electrical signal during respective time cycles, such that at least one of the circuits is operating to detect such a crossing at all times. Each circuit undergoes a reset condition, which is controlled to ensure that at least one circuit remains operating for detecting zero crossing.
