A/D converter for wideband digital communication |
摘要 |
Circuitry for providing non-uniform analog-to-digital ("A/D") signal conversion for wideband signals is provided. The circuitry of the invention is optimized for wideband signals because it does not sacrifice the small-scale resolution of high-probability signal amplitudes while preventing the clipping of low-probability signal amplitudes. The circuitry includes a nonlinear amplifier and an A/D converter that may be uniform or non-uniform. The digital output of the A/D converter may be further processed by circuitry that has an output function that is the inverse of that of the nonlinear amplifier, so as to maintain linear A/D conversion.
