Principles of Data Acquisition and Conversion (Rev A)
What are the principles data acquisition and conversion?
The sample/hold is programmed to acquire and hold each multiplexed data sample which is converted into digital form by an A/D converter.
The converted sample is then presented at the output of the A/D converter in parallel and serial digital form for further processing by the end devices.
What are the 3 components of a data acquisition system?
The components of data acquisition systems include:
Sensors, to convert physical parameters to electrical signals.Signal conditioning circuitry, to convert sensor signals into a form that can be converted to digital values.Analog-to-digital converters, to convert conditioned sensor signals to digital values.What is the principle of ADC?
The principle of charge balancing ADC is to first convert the input signal to a frequency using a voltage-to-frequency converter.
This frequency is then measured by a counter and converted to an output code proportional to the analog input.
- There are four methods of acquiring data: collecting new data; converting/transforming legacy data; sharing/exchanging data; and purchasing data.
Data acquisition and conversion systems are used to acquire analog signals from one or more sources and convert these signals into digital form for analysis or Autres questions
