Surface acoustic wave analogue matched filter realisation and applications in digital spread spectrum communications
B.J. Darby · ERA · 1974
The design of the surface acoustic wave (SAW) analogue matched filter (AMF) and the SAW non-linear convolver are examined.High performance devices are demonstrated.Potential applications are identified in burst mode transmission of data employing characteristic frequency and time domain encoded signals as address waveforms.Simple prototype modulator-demodulator configurations and their evaluation are described.
