Abstract

The possibility of using asynchronous sigma-delta modulation in primary signal converters for precision event timers is considered. A demodulation method based on the moving averaging of a signal and on using the measurements of zero-crossing instants is investigated. The moving averaging of a signal is shown to minimize the effect of timing errors on the accuracy of recovering the waveform of demodulated signals.
