Digitising Linear Measurement
Measuring current can be as simple as putting a shunt resistor in series with the circuit’s input and measuring the voltage drop using a differential amplifier; the analog voltage provided by the amp is proportional to the current and can be digitized for further processing. While this approach works fine in straightforward cases, it fails as soon as things get more complicated...
