Abstract
Adaptive filters are presented that dynamically adjust the level of filtering of signals output from a sigma-delta or noise-shaping pulse code modulator RMS-to-DC converter to efficiently remove noise to improve accuracy without unduly increasing conversion response time. The level of filtering is adjusted in accordance with criteria responsive to either input signal changes (e.g., variance), input signal frequency, or both. Filtering can be analog or digital.
