Wideband SAW (Surface Acoustic Wave) channellizer using slanted array input transducer
Abstract
An Acoustic signal processing apparatus for the frequency-partition processing of a wideband RF spectrum surface acoustic wave (SAW) input signal into a multiplicity of relatively narrowband individual contiguous acoustic wave output signals, utilizing a wideband, linearly-dispersive, slanted array input transducer arranged on a wave-conductive surface with multiple arrayed output transducers, each frequency-responsive to a respective band of frequencies emanated from the input transducer is described.
