Apodization refers to the process of removing or smoothing sharp discontinuities in mathematical functions, electrical signals, or mechanical structures. A common application of apodization is the use of a Hanning Window in Fast Fourier Transform (FFT) analysis to mitigate discontinuities at the start and end of a sample time record. This technique enhances the quality of signal processing by reducing artifacts that can distort the analysis.

Apodize
To apodize is to remove or smooth a sharp discontinuity in a mathematical function, an electrical signal or a mechanical structure. An example would be to use a Hanning Window in the FFT analyzer to smooth the discontinuities at the beginning and end of the sample time record.
