摘要： Circuitry includes a comparator to compare an input analog signal to a threshold and to output a signal that is based on the comparison; a first circuit path to receive the signal and to detect a characteristic of the signal, where the first circuit path is configured to support triggering at a first frequency; a second circuit path to receive the signal and to detect the characteristic of the signal, where the second circuit path is configured to support triggering at a second frequency that is lower than the first frequency; and a selector to select an output of the first circuit path or an output of the second circuit path.
