Designers unavailable in industrial and data-acquisition projects are likely to confront some of these analog-to-digital conversion issues:
Digitizing an input signal that extend over a very wide dynamic range, such as delivered by an environmental sound stress meter able to detect signals over a 60 to 80-dB signal range.
Accommodating signals from different source that exhibit pretty different signal ranges.
Resolving small changes approximately a certain value, so that the objective would be to get bigger the range around that point.
If a comparatively low-resolution ADC is used, say with 10 bits of effectual resolution, the high-level signal resolution would be close to 10 bits. However, for the low-level signal, if they are less than 10% of full scale, effective pledge might be no more than 6 or 7 bits.
