ABSTRACT:
A time delay corrector corrects the relative time delay or phase error between two signals, for example, stereo audio signals. A window of no correction is established between two threshold levels. So long as a signal representative of the relative phase error on a relatively fast integration basis does not logically exceed the thresholds which define this window, no rapid phase error or time delay correction is accomplished. The window of zero correction thereby prevents any time delay or phase error corrections which might otherwise result from the normal phase fluctuations inherent in the two correlated stereo signals, thereby preserving the stereo imaging and information content of those signals. Upon the occurrence of the need for a relatively major time delay error correction, such as that which originates with tape splices and the like, detection signals logically exceed the thresholds of the window and a phase correction is rapidly attained.
