Abstract
The system contains a circuit apparatus and method for monitoring the status of components within a digital system, the apparatus having a digital device. A power-line is supplied to the digital device. A second signal is rendered from the power-line. At least one mask pulse is generated from a third signal. An extraction device is situated to extract a component of the power-line. A filtering device is situated to receive the extracted component. An extracted signal is output by the filtering device, wherein the extracted signal is a correlated result having characteristics corresponding to the status of components in a digital system.
