Abstract

En un sistema receptor de una comunidad, son recibidas las ondas de radiodifusion que se multiplexan mediante ondas polarizadas de mano derecha y ondas polarizadas de mano izquierda, y estas ondas de radiodifusion se distribuyen a cada unidad terminal a través de un solo cable de señal de IF. Las ondas polarizadas de mano derecha y las ondas polarizadas de mano izquierda se convierten en señales de IF de frecuencias mutuamente diferentes mediante los convertidores 52 y 53 de bajo ruido y luego se mezclan juntas mediante un mezclador 54. Además, estas señales se mezclan con señales de difusion de television de onda terrestre por un mezclador 56 y se distribuyen a cada unidad 2 terminal a través de un solo cable de señal de IF. En la unidad 2 terminal, las señales difundidas por television de onda terrestre se separan mediante un filtro 59 de ramificacion y se alimentan a un receptor 61. Un circuito 60 de seleccion selecciona las ondas polarizadas de mano derecha y las ondas polarizadas de mano izquierda de conformidad con una señal de conmutacion de onda polarizada alimentada desde el receptor 61 y lleva a cabo la conversion de frecuencia como se requiere, y luego alimenta las ondas polarizadas al receptor 61.
