Final answer:
Frequency encoding gradient digitizes the analog signal into data points by converting the continuous variation in intensity and frequency into discrete data points.
Step-by-step explanation:
Frequency encoding gradient digitizes the analog signal into data points. The process involves converting the continuous variation in intensity and frequency of the analog signal into discrete data points so that it can be processed electronically in recording devices or computers.
Frequencies are measured in hertz (Hz), which represents the number of waves passing through a given point in a given time period. By capturing the number and relative intensity of multiple frequencies, subtle craftsmanship can lead to non-linear effects and more detail in the digital representation.
