Abstract

UN DESFASADOR DE NIVEL (600) RECIBE UNA ENTRADA DE VOLTAJE VARIABLE (VNINI), TAL COMO EL VOLTAJE REPRESENTATIVO DEL HAZ DE CORRIENTE DEL TUBO DE RAYOS CATODICOS DE UN RECEPTOR DE TELEVISION, Y PRODUCE UN VOTAJE DE SALIDA (VNIN) QUE CAMBIA CUANDO LO HACE EL VOLTAJE DE ENTRADA, DE FORMA QUE ES DESFASADO EN RELACION AL DE ENTRADA. EL VOLTAJE DE SALIDA (VNIN) ESTA ACOPLADO AL TERMINAL DE ENTRADA (+) DE UN AMPLIFICADOR DE DIFERENCIAS DE ENTRADA Y SALIDA (610) DE UN REGULADOR DE VOLTAJE DEL ALIMENTADOR DE ENERGIA. EL DESFASADOR DE NIVEL (600) INCLUYE UN ESPEJO DE CORRIENTE SENSIBLE AL VOLTAJE DE ENTRADA. UNA FUENTE DE VOLTAJE (699) DE INTERVALO DE BANDA DETERMINA EL DESFASE DE NIVEL PRODUCIDO POR EL DESFASADOR (600).
