Abstract :
An approach for the design of fractionally shifted (asymmetric) windows is presented. This approach is based on bandlimited sinc interpolation combined with oversampling techniques. The design methods are illustrated with practical examples, demonstrating that shifting of symmetric windows can be achieved while essentially maintaining the magnitude response of the window spectrum
