Family of Digital Modulaton Methods of Television Signals Wikidata
A modulation scheme that conveys data by applying amplitude modulation to two carrier waves at once. These two waves, usually sinusoids, are out of phase with each other by 90° and are thus called quadrature carriers. Commonly abbreviated QAM. Wiktionary
