Technical discussions related to Audio Signal Processing (digital effects, acoustics, noise reduction, musical signal processing, etc).
I am wondering is there is any relationship or causality between the parameters (in-phase and quadrature components) of analytic signal and modulating (information or message)-carrier signal as used in Telecommunication. Could the modulating signal like in the case of frequency modulation be taken as the real valued data while the carrier be taken as the quadrature of the modulating signal?______________________________
