    摘要: A converter continuously converts an input signal (110) to an output signal (112) even during correction and compensation. A primary converter (124) converts the signal along a forward primary path (104). A feedback converter (140) along a feedback path (106) outputs a feedback signal (116). A reference device (136) employs reference indicator (134) to provide a digital reference signal (135). A selection device (132) passes the digital reference signal (135) to an element (204) of the feedback converter (140) for outputting reference portion (208) of the feedback signal (116). The passing of the digital reference signal (135) to the element (204) is contemporaneous with the converting of the input signal (110) to the output signal (112). The evaluator (142) determines a conversion characteristic of the element (204) by employing a characteristic of the reference indicator (134).
