Abstract
EL EFECTO DE LA INTERFERENCIA DE LA SALIDA DE UNA CAMARA DE VIDEO UNIDA A UN ENDOSCOPIO 21 SE MINIMIZA POR LA SINCRONIZACION DE LA GENERACION DE PULSOS DE DIATERMIA A LA SALIDA DEL VIDEO. UNA UNIDAD DE SINCRONIZACION 11 EN EL APARATO DE DIATERMIA HACE QUE SE GENEREN PULSOS DE DIATERMIA SOLO CUANDO LA INTERFERENCIA QUE CAUSAN TIENE LUGAR EN BANDAS VERTICALES HACIA ABAJO POR EXTREMOS OPUESTOS DE LA PANTALLA MONITORA 25, FUERA DE LA REGION CENTRAL DE LA PANTALLA EN LA QUE SE REPRESENTA EL LUGAR DE CIRUGIA .
