Sigms Delta Modulator Question

Started by vinching December 11, 2006
Hi all,

If input a step respond into a SDM with a 1 bit quantizer, the output
would be a stream of '1' and '0' s. 

IS that stream PCM or PDM??
Can I tell the dynamic range form the bit stream??

For example a 50nA step input with a output bit strem of "101010111011"
and repeat.

what can I tell from these stream??

Say if I use a 1:12 decimation 
average =8/12 0.6667

Does that mean 75nA is the full scale??
