Abstract

PURPOSE: To improve a ratio of a signal to inter-band noise power by making the power spectrum of a quantized noise attenuate sufficiently near a direct current when converting a multi-level signal sampled at a long period into a binary signal sampled at a short period.
CONSTITUTION: Input terminal 1 is applied with signals in series, and a n-bit sampled value is outputted via quantization circuit 3 and digital filter 4. This sampled value is held by holding circuit 5 and inputted to integrating circuit 6. Circuit 6 accumulates inputs through n-bit fixed-point arithmetic and then, outputs its overflow
