What is the affect the resolution of an Analogue to Digital Converter on the quality of a measurement.

Expert Solution
Step 1

In measurement, resolution defines the smallest quantity that can be measured by any device. In the case of analog to digital converters, the resolution can be defined as the smallest discrete value that can be produced for a given range. The least significant bit gives the value of the resolution of the device.

Step 2

The resolution can be expressed as,
