DATA ACQUISITION SYSTEM
2
INTRODUCTION
Data Acquisition is the process of sampling
signals that measure real world physical
conditions and converting the resulting samples
into digital numeric values that can be
manipulated by a computer. Data Acquisition
System (abbreviated with the acronyms DAS or
DAQ) typical convert analog waveform into
digital values for easy processing.

NEED OF DATA ACQUISITION SYSTEM

• Data acquisition systems interface between the
  real world of physical parameters, which are
  analog, and the artificial world of digital
  computation and control.
• DAS are used widely because they are low cost,
  accurate, and relatively simple to implement.
• Data acquisition systems are capable of measuring
  hundreds of variables simultaneously.
• They are now used by most engineers and
  scientists for laboratory research, industrial
  control, test, and measurement of input and
  output data to and from a computer.

CONCLUSION
Data Acquistion Systems typically convert analog
Physical condition into Digital values for easy
processing. DAS is advantageous as we can store a
lot of physical condition data in digitized
form. DAS helps in easy processing of data as
well as easy comparison can be done. Today DAS
is used in almost every field, industry and
companies.
