QUÉ SIGNIFICA SUPERHETERODYNE RECEIVER EN INGLÉS
Receptor superheterodino
En la electrónica, un receptor superheterodino, utiliza la mezcla de frecuencias para convertir una señal recibida en una frecuencia intermedia fija, que puede procesarse más convenientemente que la frecuencia original de la portadora de radio. Fue inventado por el ingeniero estadounidense Edwin Armstrong en 1918 durante la Primera Guerra Mundial. Virtualmente todos los receptores de radio modernos usan el principio superheterodyne. A costa de una etapa de conversión de frecuencia adicional, el receptor superheterodino proporciona una selectividad y una sensibilidad superiores en comparación con diseños más sencillos.
definición de superheterodyne receiver en el diccionario inglés
La definición de receptor superheterodino en el diccionario es un receptor de radio que combina dos señales de radiofrecuencia por acción heterodina, para producir una señal por encima del límite de frecuencia audible. Esta señal se amplifica y se demodula para obtener la señal de frecuencia de audio deseada. A veces acortada a: superhéroe.

Often it is desired that the receiver output be a replica of the modulating signal
that was present at the transmitter input. There are two main classes of receivers:
the tuned radio frequency (TRF) receiver and the superheterodyne receiver.
