What is a 50% overlapping technique?

A technique utilized while applying a polish or protection where each pass overlaps the previous pass by 50% to ensure thorough application.

What is overlap in FFT?

FFT convolution uses the overlap-add method together with the Fast Fourier Transform, allowing signals to be convolved by multiplying their frequency spectra. For filter kernels longer than about 64 points, FFT convolution is faster than standard convolution, while producing exactly the same result.

Why do we use overlap in FFT?

FFT processing can be particularly problematic when the signal consists of randomly occurring transients superimposed on a more continuous signal. Overlap processing is commonly used in this situation to improve the estimates.

Why do we use overlap?

Overlap is a parameter used when determining the way time data is to be processed and converted into the frequency domain. It can have a big effect on the results, so understanding overlap is critical to a successful data processing session.
