Analogous processors with surface acoustic waves Zdravko R. Živković The principles of development and implementation of
processors with chirp filters with sur face acoustic waves (SAW) are presented.
The analysis of their working principles has shown that in specific
configurations of these analogous processors, a complex signal processing in a
wide frequency range (dozens of MHz) can be per formed, which makes them
suitable for applying in radars, sonars and communication devices. Further more,
the possibility of applying SAW processors as spectral and network analysers has
been taken into consideration. Finally, it is presented how some more
sophisticated functions of signal processing such as kepstral analysis and
adaptive filtering, can be realised through
combining a number of processors.
