Abstract
Apparatus is configured for producing an output signal indicating an operating status of a monitored circuit. An input signal relating to the monitored circuit is received at an input node. A pulse train generator, coupled to the input node, is configured for generating a pulse train of a prescribed repetition rate at a duty cycle alternated between first and second duty cycle values at a prescribed frequency. The duty cycle and frequency are indicative of operating status of the monitored circuit.
