Apodization

Apodize, Apodization

Literally, "to remove the foot". To apodize is to remove or smooth a sharp discontinuity in a mathematical function, an electrical signal, or a mechanical structure. An example of apodization is the use of the Hanning window in the FFT analyzer to smooth the discontinuities at the beginning and end of the sampled time record. When stopping your car, if you reduce the brake pedal force just as you come to a stop, you will not feel a "jerk" and the car will come to a smooth stop. This is a form of apodization.
