Signal processing using surface acoustic waves
Abstract
Surface acoustic wave devices can be used for pulse compression, variable-bandwidth filtering, matched filtering, variable time delay, adaptive filtering, correlation, convolution, or Fourier transformation, in addition to the basic filtering and frequency control. These applications are discussed, centering on the signal processing using dispersive delay lines, fixed correlators, and programmable correlators and convolvers. The major advantages of the surface wave acoustic components are noted to be the real-time processing capability, small size, and simplicity, though their dynamic range is limited.
