Problems in design and analysis of practical SAW CZT spectrometer

Though there have been a large number of studies on surface acoustic wave chirp z transform processors in their operating principle, it still is a necessary step to demonstrate their practicability in the use of real time signal processing. In this paper a couple of practical problems in design and analysis of SAW CZT spectrometer, such as the definition of frequency resolution, the choise of available data postprocessing technique and the analyses of it's noise behaviour and temrpeture stability etc., will be gone through.
