TY - JOUR TI - Description of a 2-bit adaptive sigma-delta modulation system with minimized idle tones AU - Prosalentis, E. A. AU - Tombras, G. S. JO - EURASIP Journal on Advances in Signal Processing PY - 2008 VL - null TODO - null SP - null PB - SpringerOpen SN - 1687-6172, 1687-6180 TODO - 10.1155/2008/426502 TODO - null TODO - A 2-bit adaptive sigma delta modulation system that inherently eliminates the idle tones present in conventional and other adaptive sigma delta systems is described. The system incorporates both memory and look-ahead instantaneous step-size estimations and, as shown by computer simulation results apart from eliminating the unwanted idle tones despite dithering, it offers improved SNR performance and extended dynamic range.
