Analogue & Digital Data

• Analogue data is continuous and varies smoothly over time

• Digital data is discrete and represented in binary form (Os and 1s)

Differences between Analogue & Digital Data

• Analogue data can have any value within a range, while digital data has a limited set of values

• Digital data is less prone to noise and distortion compared to analogue data

• Digital data can be easily manipulated, stored, and transmitted by computers

Converting Analogue to Digital Data

• Analogue data must be converted to digital data so it can be processed by a computer

• This process is called analogue-to-digital conversion (ADC) and is performed by an analogue-to- digital converter

Converting Digital to Analogue Data

• Digital data must be converted to analogue data so it can be used to control devices

• This process is called digital-to-analogue conversion (DAC) and is performed by a digital-to- analogue converter
