Abstract: In a digital-to-analog converter for bipolar signals all the bits change when the signals pass through the zero level. This results in a poor signal-to-noise ratio owing the small signal and the large noise contribution by the switching transients. The invention proposes to add a digital number to or subtract it from the digital input signal as an offset. As a result of this, the switching point is shifted towards a higher amplitude, which improves the signal-to-noise ratio and the distortion in the case of digital audio signals.

Abstract: Tracking apparatus and related method for use in a playback system for recovering information from a selected recording track on an optical record medium such as a video disc (13). The tracking apparatus produces a tracking error signal representative of the deviation of a scanning reading beam (11) from the centerline of the selected track, and couples this error signal to a movable tracking mirror (21) to form a servo for controllably positioning the beam in alignment with the track. The tracking apparatus further includes a defect detection circuit (41) for monitoring the tracking error signal and producing a pair of control signals that indicate when video disc defects of prescribed types are being scanned, and a threshold detector circuit for comparing the error signal to prescribed positive and negative thresholds that are selectively-variable in accordance with the pair of control signals. A tracking loop disable signal is produced whenever the magnitude of the error signal exceeds either threshold, and this disable signal is used to uncouple the tracking error signal from the tracking mirror, so that the reading beam is maintained at its current position until the dimple has been passed.
