摘要: A semi-uniform quantizer for multi-bit sigma delta modulator is proposed. It has smaller quantization steps inputs and vice versa. The use of a k-bit achieves roughly the same performance as using (k+1)-bit uniform over main part input signal dynamic range. can easily be constructed in way constructing quantizer.
