Abstract

The frequency characteristics of commercially generated A.C. line supplies are generally known to be extremely precise over a long period of time. Many consumer clock circuits use this fact to achieve a high degree of accuracy in their time keeping chore. Unfortunately, this high stability is lost when the power line fails.
