Abstract

Perfeccionamientos introducidos en un convertidor de digital en analógico, en donde en un circuito de comparación es comparada una combinación de señales de entrada que corresponde a un número digital con una combinación de señales que corresponde a una serie de números que se presenta periódicamente, cuya combinación de señales es generada por un circuito contador que está controlado continuamente por un impulso de sincronismo, cuyo circuito de comparación genera una señal de salida en forma de impulso cuyo valor medio corresponde con el valor del número digital a ser convertido, caracterizados porque el circuito de comparación es un circuito de comparación secuencial en el cual son comparadas sucesivamente señales correspondientes a cada una de las cifras del número digital con las correspondientes a las cifras de la serie de números producida por el circuito contador.
