| Outline of Final Research Achievements |
To enter signals into digital devices, signals are sampled and quantized. Quantization is to convert continuous-valued signals into discrete-valued signals that can take only a finite number of discrete values.
In quantization, so-called quantization errors are generated. We analyze and synthesize the quantization by easily realizable Delta-Sigma modulators having a relatively simple structure. We analytically evaluate the effect of quantization errors on the system and develop designs of Delta-Sigma modulators to minimize the effect.
