The technique of adding zeros to the end of the free induction decay before transformation is called _____ filling.
Answer: B
Zero filling appends zeros so the transform yields more points per hertz and the line is defined more finely. It improves digital resolution without adding information, and doubling the data size once is generally worthwhile while further doubling gains little. Phasing corrects the mixture of absorption and dispersion in the displayed lineshape, line broadening is the exponential apodisation, and baseline correction fits and subtracts a slow roll. The four operations are separate steps of the same processing chain.
