On the theoretical possibility to apply an acoustic diffraction grating as a complex frequency filter device for electronic signals

In electronics, it is well known that filtering devices can be made that are able to decompose a signal instantaneously into a number of real frequency components. This procedure is equivalent to a numerical real time Fourier transform. However, it is also known that an electronic signal can be deco...
