Abstract

CIRCUITO SINTETIZADOR POLIFONICO. UN DISPOSITIVO TRADICIONAL DE PRODUCCION DE SEÑALES DE EXPLORACION ANALOGICA Y UN DISPOSITIVO DE MANDO QUE GOBIERNA ESA PRODUCCION. EL DISPOSITIVO DE MANDO ESTA CONSTITUIDO POR UN CADENCIOMETRO ACOPLADO A UN CONTADOR NUMERICO, UN ALMACENAMIENTO QUE RETIENE UN NUMERO REPRESENTATIVO DEL SEMIPERIODO DE LA SEÑAL FUNDAMENTAL, UN ALMACENAMIENTO DE ACONTECIMIENTO QUE CONTIENE UN NUMERO QUE CORRESPONDE AL INSTANTE A PARTIR DEL CUAL SE HA DE PRODUCIR EL VALOR DE EXPLORACION DE LA SEÑAL, UN COMPARADOR QUE COMPARA EL ESTADO DEL CONTADOR CON EL CONTENIDO DEL ALMACENAMIENTO DE ACONTECIMIENTO.
