1 Windowing Introduction ... If our signal is a lowpass or passband signal, the application of a window will introduce high-frequency components. Power from the original signal will be diverted from the specified frequency band into the high-frequency areas.

"A nieve approach, the rectangular window, involves simply truncating the dataset before and after the window, while not modifying the contents of the window at all. However, as we will see, this is a poor method of windowing and causes power leakage."

Introduction to DSP - frequency: windowing I ... If we only measure the signal for a short time, the Fourier Transform works as if the data were periodic for all time. ... If not quite an integral number of cycles fit into the total duration of the measurement, then when the Fourier Transform assumes the signal repeats,

Signal Windowing to Reduce DFT Leakage ... Lyons shows how windowing can reduce DFT leakage that would otherwise obscure signal components. However, the opposite can also true. For two signals that are close to each other in frequency, where one signal is smaller than the other, windowing can obscure a signal component.

Signal windowing is a temporal weighting operation whereby a signal is multiplied by a function that pays more emphasis on desired parts of the signal and typically attenuates it outside this span, normally to zero, in order to result in a finite support (nonzero part).

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.
