The Gaussian function is for $${\displaystyle x\in (-\infty ,\infty )}$$ and would theoretically require an infinite window length. However, since it decays rapidly, it is often reasonable to truncate the filter window and implement the filter directly for narrow windows, in effect by using a simple rectangular window … See more In electronics and signal processing mainly in digital signal processing, a Gaussian filter is a filter whose impulse response is a Gaussian function (or an approximation to it, since a true Gaussian response would have See more • GSM since it applies GMSK modulation • the Gaussian filter is also used in GFSK. • Canny Edge Detector used in image processing.
