1 bit converter

As the designation 1-bit converter already indicates, such converters only work with a single bit

, which can assume the values "0" or "1". 1-bit converters form the analog-to-digital conversion of sigma-delta conver

ters. In order to achieve high resolutions at all, the sampling frequency of

1-bit converters is many times higher than that of multi-bit converters.After that, a resolution of 16 bits can be achieved with a sampling rate that is sixteen times higher.

With the 1-bit converter, only the level differences from one sample to the next are marked with the A/D conversion. If a sample value is higher than the previous one, a digital "1" is indicated; if the level continues to rise, the following sample value is also a "1". Only when the level is falling, the "1" is replaced by a "0".
