Spectral Analysis of MRI Sound Signal
Abstract
The article presents selected acoustic power amplifiers, among those currently available. The results of a series of measurements characterizing the amplifiers are presented. The measured amplitude and phase characteristics as a function of frequency for four selected amplifiers are analysed. The spectra of the output signal in the band from 4 to 30 kHz are presented. The usefulness of the selected amplifiers in the underwater communication system is assessed.
