Signal Processing with Saw Devices. [PDF]
, 1978 Abstract : The use of surface acoustic wave devices to perform real time Fourier transformation for time-limited signals is well known. In this paper a detailed analysis justifying the implementation most typically employed will be presented, as the description of a scheme which extends the above technique by allowing the transformation of a long ...
