Abstract: PURPOSE:To obtain an analog output with high S/N by forming a signal quantized by a resolution smaller than that of an input signal into a differentiated value having a further smaller resolution by a digital differentiating device, D/A-converting the result and integrating it. CONSTITUTION:An input digital signal is subjected to interpolation to increase the sampling frequency by a digital filter 2, an n1-bit resolution is obtained and the result is fed to a differentiating modulator DELTAMOD8.
