Sequential comparisons in series-connected stages with no change in value of analogue signal

Introduced: January 1985

Full Title

Full titles differ between systems:

IPC:

Analogue/digital conversion; Digital/analogue conversion > Analogue/digital converters > Analogue value compared with reference values > sequentially only, e.g. successive approximation type > Sequential comparisons in series-connected stages with no change in value of analogue signal

CPC:

Analogue/digital conversion; Digital/analogue conversion (conversion of analogue values to or from differential modulation H03M3/00) > Analogue/digital converters ( H03M1/10 take precedence) > Analogue value compared with reference values (H03M1/48 takes precedence) > sequentially only, e.g. successive approximation type (converting more than one bit per step H03M1/14) > Sequential comparisons in series-connected stages with no change in value of analogue signal

No child classifications to compare. This is a leaf node in both IPC and CPC.
