Abstract
The paper presents one kind of filter based on fractional Fourier transform for one dimensional signal. Compared with other one-dimensional filters, this filter can improve the edge effect before and after filtering. Not only has high signal-to-noise ratio, but also there is no leak at signal of two terminals. When calculating the signal-to-noise ratio, I take four examples with low noise to high noise. Through MATLAB simulation, it shows that has excellent filter characteristics and is very suitable for signal processing.
