Abstract

AMPLIFICADOR TRANSITORIZADO DE GANANCIA CONTROLADA. ESTA FORMADO POR UNOS TRANSISTORES DE AMPLIFICACION (10 Y 12), UNA SERIE DE RESISTENCIAS (18,20,22,24,26,28 Y 30), UNOS DISPOSITIVOS DE RESITENCIA CONTROLADA (14 Y 16) Y UNA FUENTE DE CORRIENTE DE CONTROL DE GANANCIA (40). TANTO LOS TERMINALES BASE DE LOS AMPLIFICADORES COMO LOS DE LOS DISPOSITIVOS DE RESISTENCIA CONTROLADA SE CONECTAN, A TRAVES DE RESISTENCIAS, A UNAS FUENTES DE TENSION (V Y B +). EXISTEN DIFERENTES ALTERNATIVAS DE REALIZACION. DE APLICACION EN RECEPTORES DE TELEVISION.
