Abstract

Un aparato receptor o emisor de una gama de frecuencias extensa que contiene un oscilador de variación continuo de longitud de onda en límites mucho mas estrechos que los de la gama recibida o emitida; caracterizado porque la gama recibida o emitida; caracterizado porque la gama recibida o emitida se subdivide en trozos cuya anchura es igual como máximo a la gama cubierta por el oscilador disponiéndose medios de conmutación para pasar de un trozo a otro y por que se disponen uno ovarios pasos de cambio de frecuencia con ayuda de osciladores de frecuencia fija muy estable entre el circuito de recepción o de emisión y el circuito del oscilador de frecuencia variable eligiéndose los valores de las frecuencias fijas de estos osciladores de tal manera que los límites de gama del oscilador de frecuencia variable y los límites de trozos de frecuencia en el paso cambiador de frecuencia inmediatamente vecino ofrecen una diferencia fija constante para todos los trozos.A receiver or transmitter apparatus of a wide frequency range that contains a continuously varying wavelength oscillator in limits much narrower than those of the received or emitted range; characterized in that the range received or emitted; characterized in that the received or emitted range is subdivided into pieces whose width is at most equal to the range covered by the oscillator, providing switching means to go from one piece to another and in that one or several frequency change steps are arranged with the help of very stable fixed frequency oscillators between the receiving or transmitting circuit and the variable frequency oscillator circuit, the values of the fixed frequencies of these oscillators being chosen in such a way that the range limits of the variable frequency oscillator and the bit limits frequency in the immediately neighboring frequency changer step offer a constant fixed difference for all chunks.
