Signal Analysis Using the Acousto-Optic Spectrum Analyzer

摘要

This paper examines the instantaneous, Fourier power spectrum for different types of input signals such as CW, pulse modulated CW and linear FM signals using the acousto-optic spectrum anlayzer. The effect on the time-integrated output intensity distribution due to the truncation of the propagating acoustic signal by the finite aperture width of the Bragg cell is also analyzed. Some experimental results on pulse-modulated CW and linear FM signals are presented, and then compared with theory. (Author)
