Abstract
The invention relates to a digital circuit arrangement which comprises an interpolation filter which over samples a digital input signal, a noise shaper (1) following the interpolation filter (1), and a digital-to-analog converter coupled to the output of the noise shaper. The noise shaper includes a quantizer whose output signal is the output signal of the noise shaper. A quantization-error signal is formed which is passed through a limiter, filtered and added to the output signal of the interpolation filter to provide correction.
