Renseignements obtenus de la compagnie Motorola, à Montréal. Cette firme a elle-même mis au point le dispositif à semi-conducteurs utilisé par le procédé C-QUAM (Compatible Quadrature Amplitude Modulation). Noter que «compatible» qualifie «Amplitude Modulation», laquelle modulation d'amplitude s'appliquant aux signaux (des voies droite et gauche) déphasés d'un quart de période (on dit alors «diphasés» ou «en quadrature»). Noter aussi que «compatible» sous-entend le syntagme «avec la stéréophonie». 1, record 3, French, - modulation%20d%26rsquo%3Bamplitude%20compatible%20de%20signaux%20en%20quadrature
