4.1 Digital signals
The output from most sensors tends to be in analogue form, the size of the output being related to the size of the input. Where a microprocessor is used as part of the measurement or control system, the analogue output from the sensor has to be converted into a digital form before it can be used as an input to the microprocessor. Likewise, most actuators operate with analogue inputs and so the ...
