ABSTRACT:
A drop-out detector circuit for use in a device such as a video disc player or the like is provided using a minimum of added components. The input analog signal read from the disc is compared with the upper and lower (maximum and minimum) reference levels provided for the A/D converter otherwise provided for converting the input analog signal to digital form. When either limit is exceeded, a drop-out signal is generated.
