QUÉ SIGNIFICA PHASE MODULATION EN INGLÉS
Modulación de fase
La modulación de fase es un patrón de modulación que codifica información como variaciones en la fase instantánea de una onda portadora. A diferencia de la modulación de frecuencia, la modulación de fase no se utiliza ampliamente para transmitir ondas de radio. Esto se debe a que PM requiere hardware de recepción más complejo, y puede haber problemas de ambigüedad para determinar si, por ejemplo, la señal ha cambiado de fase por + 180º o -180º. PM se utiliza para la generación de señales y formas de onda en sintetizadores digitales, como los sintetizadores Casio CZ, y para implementar la síntesis FM en sintetizadores digitales como el Yamaha DX7.
definición de phase modulation en el diccionario inglés
La definición de modulación de fase en el diccionario es un tipo de modulación, utilizado en los sistemas de comunicación, en el que la fase de una onda portadora de radio se varía en una cantidad proporcional a la amplitud instantánea de la señal de modulación.

This is known as phase modulation (PM). When a carrier is phase modulated, the
input signal is designed to alter the phase of the carrier. When the amplitude of
the modulating signal swings positive, the greater is the phase shift of the carrier
