What we have learnt
- Counter-type A/D converters have variable conversion times defined as the time taken for complete analog-to-digital conversion.
- The digital output of an A/D converter can be determined based on the voltage input and the conversion characteristics of the device.
- A/D converters play a vital role in systems that require the digitization of analog signals for processing and storage.
Key Concepts
- -- A/D Converter
- A device that converts an analog signal into a digital signal.
- -- D/A Converter
- A device that converts a digital signal into an analog signal.
- -- Resolution
- The smallest change in the input voltage that can cause a change in the output code.
- -- Conversion Time
- The time taken to convert an input analog signal to its corresponding digital output.
- -- Quantization Error
- The difference between the actual analog voltage and the quantized digital voltage value.
