Abstract
2.1.- EL AJUSTE AUTOMATICO DE LA CORRIENTE DE REGIMEN DE REPOSO EN UN PASO DE SALIDA EN CONTRAFASE SE CONSIGUE DE TAL MANERA, QUE SE PREVEE EN CADA RAMO DEL PASO DE SALIDA UN ELEMENTO PALPADO. LAS DOS TENSIONES MEDIDAS SOBRE LOS ELEMENTOS PALPADORES CONTRA EL POTENCIAL DE REFERENCIA SE INDICAN SOBRE UN PASO AMPLIFICADOR DE DIFERENCIA, CUYA TENSION DE SALIDA SE COMPARA CON EL VALOR DE REFERENCIA CON LA AYUDA DE UN COMPARADOR. LA CONEXION MUESTRA UNA DEPENDENCIA DE LA FRECUENCIA DE LA REGULACION DE CORRIENTE DE REPOSO AUTOMATICA A CONSECUENCIA DE LA FRECUENCIA LIMIATADA DEL TRANSISTOR FINAL. 2.2.- PARA EVITAR ESTA DEPENDENCIA DE LA FRECUENCIA, SE CONECTA UNA ARTICULACION GIRATORIA DE FASES SOBRE UNA ENTRADA DEL AMPLIFICADOR DE DIFERENCIA, QUE EMPEORA LA SUSPENSION DE CADENCIA SINCRONICA DEL AMPLIFICADOR DE DISTANCIA EN FRECUENCIAS ALTAS. A TRAVES DE ESTA MEDIDA SE CONSIGUE QUE SE COMPENSE EL DEFECTOR DEPENDIENTE DE LA FRECUENCIA. 2.3.- GRADOS FINAL DE CADENCIA CONTRARIA CON REGULACION DELA CORRIENTE DE REGIMEN DE REPOSO.
