Abstract
A new technique is presented for dithering single bit sigma-delta modu lator (SDM) A/D and D/A converters in the digital domain. The system o perates by detecting and randomising the Iimit cycle oscillations resp onsible for baseband tones. The system is efficient to implement in ha rdware and does not suffer from the analogue dither that is required i n conventional SDM A/D converters.
