In this paper. a theoretical calculation of a radio-photon mixer is performed using spectral analysis of signals and the results of an experimental study of the spectral composition of optical signals in a radio-photon mixer. An experimental setup consisting of a source of optical radiation. two Mach - Zehnder modulators. https://www.spidertattooz.com/Superdry-Organic-Cotton-Essential-Baseball-L-S-T-shirt/
