Abstract

UN CIRCUITO DE FILTRADO USA UN CONTADOR REVERSIBLE (31) PARA ELIMINAR RUIDOS DESDE LA SEÑAL DE ENTRADA (5) LA CUAL CAMBIA ENTRE ALTOS Y BAJOS NIVELES. LA SEÑAL DE ENTRADA (5) ES MOSTRADA EN RESPUESTA A UNA SEÑAL DE RELOJ (7) DE FRECUENCI SELECCIONADA Y UN CONTADOR REVERSIBLE ES INCREMENTADO POR UN VALOR MOSTRADO A BAJO NIVEL. UNA HISTERISIS ES CONSTRYUIDA DENTRO DE LA SECUENCIA CONTADORA POR VIBRACION LA CUENTA POR UN PREDETERMINADO VALOR CUANDO LA CUENTA ES INCREMENTADA SOBRE UN PRIMER VALOR UMBRAL.
