What is windowing in FFT?
Windowing reduces the amplitude of the discontinuities at the boundaries of each finite sequence acquired by the digitizer. Windowing consists of multiplying the time record by a finite-length window with an amplitude that varies smoothly and gradually toward zero at the edges.
What is windowing a signal?
The process of windowing a signal involves multiplying the time record by a smoothing window of finite length whose amplitude varies smoothly and gradually towards zero at the edges. The length, or time interval, of a smoothing window is defined in terms of number of samples.
What is windowing in DFT?
Lecture 5 - DFT & Windowing. Page 1. In this lecture, I will be examining the impact of extracting a portion of a signal and find the spectrum of this extracted portion instead of the signal. This process of taking a portion of signal is known as “windowing”.
