Calculating Group Delay in Delta Sigma Converters
Delta-sigma converter group delay equals the phase derivative across decimation filter stages, calculated as K times M minus one divided by twice the modulator clock for sinc filters.
Aligning Moving Average Windows with Converters to Eliminate Aliasing Artifacts
Aligning moving average window lengths to match converter sample periods places exact spectral nulls over periodic interference to eliminate aliasing artifacts.
Dual Sourced Low Tier Commercial Sensor Supply Exposure
Dual-sourcing low-tier commercial sensors introduces baseline offset drift, thermal hysteresis, and ASIC filtering divergence that increase total landed product cost.
Power Budget per Reading across Competing Sensing Principles
Sensing power budgets depend on physical excitation energy, analog settling delays, and converter sampling overhead across operating duty cycles.
Quantifying Phase Margin Loss from Cascaded Sinc and Boxcar Filter Window Delay
Cascaded sinc and boxcar filter window delays introduce deterministic group delays that subtract directly from control loop phase margin at crossover frequencies.
Integrating Moving Average Filter Windows with Analog Converter Downsampling Rates
Aligning moving average filter lengths as integer multiples of ADC decimation rates eliminates aliasing foldover and maximizes noise bandwidth reduction.
