Vector quantization view of /spl Sigma//spl Delta/ modulation

We analyze the behavior of a single-loop /spl Sigma//spl Delta/ modulator using a vector quantization (VQ) approach. We extract the encoder-decoder structure typical of VQ, existing in a /spl Sigma//spl Delta/ modulator. The study of the encoding part gives the intrinsic behavior of the modulator. Bounds to the intrinsic performance of the /spl Sigma//spl Delta/ modulator can be derived through this approach in the oversampling situation, assuming periodicity of the bandlimited input signals.<
