Abstract
A power monitoring system with associated signal processing and storage capabilities. An input signal is sampled and the samples are compared to a threshold to identify an impulse. The system analyzes the length of each impulse to dynamically adapt a memory storage size to store a number of samples occurring during an impulse period. In a further embodiment, the input signal must remain below a second threshold for a fixed number of samples before storing of the samples is terminated.
