Abstract
A drop-out detector circuit for use in a data reproducing device in which a reproduced high-frequency signal is digitized. The most significant bit of the digitized signal is sampled, and its logic state detected over a predetermined number of sampling periods. Both high- and low-frequency drop-outs can be detected from the detected logic state pattern of the most significant bit.
