The dual-slope conversion improvement
The dual-slope ADC (DSADC) is a type of analog-to-digital conversion with low input bandwidths. It is pretty slow, but its ability to reject high-frequency noise and fixed low frequencies such as 50 Hz or 60 Hz makes it useful in noisy industrial environments and applications. It provides...

| Summary: | The dual-slope ADC (DSADC) is a type of analog-to-digital conversion with low
input bandwidths. It is pretty slow, but its ability to reject
high-frequency noise and fixed low frequencies such as 50 Hz or 60 Hz makes
it useful in noisy industrial environments and applications. It provides
very good resolution. For the practical measurements in the Institutes
laboratory an instrument is designed and realized. The base DSADC method is
used, but improved by multiple conversions to make the measuring more
precise and the time shorter. The special attention is paid to the problems
occurred in practical realization and the way to overcome them. The paper
describes the proposed and applied solutions, functional principles and
achieved performances of the realized instrument. [Projekat Ministarstva
