Abstract

UN AMPLIFICADOR RESPONDE A UNA FUENTE DE SEÑAL 38 QUE TIENE UN ESPECTRO PREDETERMINADO Y AMPLITUD MAXIMA PREDETERMINADA. EL AMPLIFICADOR COMPRENDE AL MENOS VARIAS FASES 209.1-209.48, 122.1122.48 ACTIVADAS SOLAMENTE EN UNO DOS ESTADOS BI-NIVEL CONTROLADOS EN RESPUESTA AL VALOR DE LA FUENTE QUE EXCEDE UN UMBRAL PARA CADA FASE, CADA FASE TENIENDO UN UMBRAL DIFERENTE, DICHOS UMBRALES Y FUENTE ESTANDO DISPUESTOS PARA QUE LAS FASES CAMBIEN ENTRE DICHOS ESTADOS BI-NIVEL MIENTRAS EL VALOR DE LA FUENTE CAMBIA RELATIVO A LOS UMBRALES DE LAS DIFERENTES FASES, SALIDAS BI-NIVEL ASOCIADAS CON LOS ESTADOS DE ALTO NIVEL DE LAS FASES PLURALES QUE SON SUMADOS JUNTOS 121, Y UN OSCILADOR 64 PARA DERIVAR UNA SALIDA DE VARIACION CONTINUA PARA VARIAR LOS VALORES DE LOS UMBRALES, LA SALIDA TENIENDO UN VALOR PICO A PICO PEQUEÑO RELATIVO A LA AMPLITUD MAXIMA PREDETERMINADA, LA SALIDA DE OSCILADOR INCLUYENDO FRECUENCIAS VARIABLES, ALGUNAS DE LAS FRECUENCIAS VARIABLES TENIENDO UNA TENDENCIA A INTRODUCIR UN NIVEL DE RUIDO PERCEPTIBLE EN LAS SALIDAS DE LAS FASES SOBRE EL ESPECTRO PREDETERMINADO. EL AMPLIFICADOR TIENE ELEMENTOS 70, 72 PARA EXPANDIR EL NIVEL DE SONIDO EN UN ESPECTRO MAS AMPLIO Y REDUCIR DICHO NIVEL DE SONIDO EN FRECUENCIAS ALTAS EN EL ESPECTRO PREDETERMINADO.
