ABSTRACT:
In a digital-to-analog conversion circuit, a level detector is used to determine when the digital signal is lower than a predetermined value. When a predetermined time has expired, after the level detection, an inversion detector detects an inversion in polarity of the digital signal. As a result, a control signal is produced to shift the digital signal input to the digital-to-analog (D/A) converter and to attenuate the output analog signal.
