What effect does increasing the digitizing frequency have on A-scan acquisition?

Increasing the digitizing frequency has a significant impact on A-scan acquisition, primarily by improving signal clarity. When the digitizing frequency is increased, more data points are collected in a given time period. This results in a more detailed representation of the signal, capturing higher frequency components and variations.

As a result, the resolution of the A-scan is enhanced, allowing for better identification of features within the signal. Higher digitizing frequencies can minimize the occurrence of aliasing, where higher frequencies are misrepresented, thus enhancing the fidelity of the data being recorded.

Increased digitizing frequency does not inherently distort the data being acquired but rather facilitates a more accurate and clearer visualization of the signal's characteristics. This clarity is crucial in non-destructive testing, where distinguishing subtle differences in materials or defects can be vital for accurate evaluations.
