Digitization is the creation of digital signals from analogue originals by means of dedicated electronic systems. Modern instrumentation uses this process to show signals on their live displays and store data. Digitization parameters are essential variables that affect NDE detection and measurements.

Why are signals digitized?
Digital signals can convey information with less noise, distortion, and interference. Digital circuits can be reproduced easily in mass quantities at comparatively low costs. Digital signal processing is more flexible because DSP operations can be altered using digitally programmable systems.
How is digital signal generated?
To create a digital signal, an analog signal must be modulated with a control signal to produce it. The simplest modulation, a type of unipolar encoding, is simply to switch on and off a DC signal so that high voltages represent a '1' and low voltages are '0'.
What is an example of a digital signal technology?
Digital computers and digital phones are some of the examples of digital signals.
