SAW Implemented Real-Time Hilbert Transform and Its Application in SSB
Pankaj Kumar Das, D. Shklarsky, L.B. Milstein · 1979
Following the already known SAW chirp realtime transforms (Fourier and Fresnel), the capability of computing real-time Hilbert transforms using chirp devices is demonstrated in this work. The Hilbert transf6rm is computed by multiplication of the Fourier transform by the signum function (with arbitrary frequency origin) before inverse Fourier transformation. Once the Hilbert transform is achieved, single sideband (SSB) modulation is its natural byproduct. Comparisons of this SSB method to the two most common conventional SSB generation techniques are presented. Finally, experimental results of Hilbert transforms are presented together with results of SSB modulation.
