abstract:A phase switch is a device used to increase the discrimination and sensitivity of an interferometer, especially at radio frequencies; an extra half-wave path difference is switched in, at well defined frequency, between the two interfering signal sources. In-phase signals then become out of phase and vice versa, so that the signal output becomes modulated by the switching frequency, and can be more easily filtered from the internally generated noise.
But that will change with the Internet's next phase, when the main platform will switch from the PC to the Internet itself, and in which hosted services will emerge and the economy will move online, he said.
