Abstract
Perfeccionamientos en circuitos transformadores de señal de video, caracterizados porque se disponen, un divisor de fase que tiene una entrada que responde a la señal de video y un par de impedancias de carga resistivas para desarrollar versiones de fases opuestas de las señales de video a través de las impedancias respectivas del par de impedancias de carga resistivas, un terminal de salida para la etapa de transformación de la señal, medios que comprende una primera impedancia reactiva, para acoplarse señales desarrolladas a través de una de las impedancias de carga al terminal de salida, medios que comprenden una segunda impedancia reactiva opuesta en signo de reactancia a la primera impedancia reactiva, para acoplarse señales desarrolladas a través de la otra de las impedancias de carga al terminal de salida, y porque los parámetros de las impedancias reactivas se eligen para hacer que la etapa de transformación de la señal presente una característica de retardo contra frecuencia no lineal que tiene la forma deseada sobre la gama de las frecuencias ocupada por las señales de video, y medios para variar la característica de respuesta de amplitud contra frecuencia de la etapa de transformación de la señal sin perturbación sustancial de la forma de su característica de retardo contra frecuencia, comprendiendo los medios citados medios para variar el valor de la impedancia de carga resistiva.
