Abstract
CIRCUITO DE CONMUTACION CON VARIAS ENTRADAS Y UNA SALIDA. UNOS CONMUTADORES (22, 23, 24) QUE PUEDEN SER MECANICOS O ELECTRONICOS, PERMITEN SITUAR UNOS TRANSISTORES (14, 16) EN ESTADO DE PODER CONDUCIR; SIN EMBARGO, NO ES POSIBLE DEBIDO A QUE EL NIVEL DE REFERENCIA DE LAS SEÑALES DE ENTRADA (S1. S3) NO DEJA CONDUCIR A LOS TRANSISTORES (8, 10, 11, 13) QUE LAS CONTROLAN. DE OTRO LADO, UN TRANSISTOR (15) ESTA CONDUCIENDO UNA CORRIENTE SUMA DE LA QUE PASA POR LOS TRANSISTORES QUE CONTROLAN UNA SEÑAL DE ENTRADA (S2); AL ESTAR ESTOS EN CONDUCCION, DICHA SEÑAL DE ENTRADA (S2), PRESENTE EN LA BASE DE UNO DE LOS TRANSISTORES (9), PASA A LA DEL OTRO TRANSISTOR (12) Y, POR TANTO, A LA SALIDA (4). DE ESTA FORMA, SEGUN EL ESTADO DE LOS CONMUTADORES (22, 23, 24) SE OBTIENE EN LA SALIDA (4) UNA DE LAS ENTRADAS PRESENTES (1, 2, 3). EL CIRCUITO PERMITE UNA REDUCCION ADICIONAL DE LA DIAFONIA. DE APLICACION EN LOS SISTEMAS DE VIDEO.
