Abstract

UN PROCESADOR DE SONIDOS DIFUSOS QUE INCLUYE UN CIRCUITO PROCESADOR DE CONSTANTE DE TIEMPO (56) PARA SUAVIZAR LAS SEÑALES DE INFORMACION SOBRE LA DIRECCION DE UN DETECTOR (54) CON CONSTANTES DE TIEMPO CONTINUAMENTE VARIABLES PARA GENERAR UNA O MAS SEÑALES DE TENSION DE CONTROL. LAS CONSTANTES DE TIEMPO PRODUCIDAS POR EL CIRCUITO SON CONTINUAMENTE VARIABLES Y RESPONDEN TANTO A LA VELOCIDAD DE CAMBIO COMO A LA AMPLITUD DE LAS SEÑALES DE INFORMACION SOBRE LA DIRECCION, DE MODO QUE A MEDIDA QUE AUMENTA LA DIFERENCIA ENTRE LAS SEÑALES DE TENSION CONTROLADAS Y LAS SEÑALES DE INFORMACION SOBRE LA DIRECCION, EL VALOR DE LAS CONSTANTES DE TIEMPO DISMINUYE PARA PERMITIR QUE LAS SEÑALES DE TENSION DE CONTROL SIGAN DE CERCA A LAS SEÑALES DE INFORMACION SOBRE LA DIRECCION Y A MEDIDA QUE DISMINUYE LA DIFERENCIA ENTRE LAS SEÑALES DE TENSION DE CONTROL Y LAS SEÑALES DE INFORMACION SOBRE LA DIRECCION, EL VALOR DE LAS CONSTANTES DE TIEMPO AUMENTA DE MODO QUE LAS VARIACIONES EN LAS SEÑALES DE TENSION DE CONTROL SON SUAVES.A DIFFUSE SOUND PROCESSOR INCLUDING A TIME CONSTANT PROCESSING CIRCUIT (56) TO SOFTEN THE INFORMATION SIGNALS ABOUT THE DIRECTION OF A DETECTOR (54) WITH CONTINUALLY VARIABLE TIME CONSTANTS TO GENERATE ONE OR MORE CONTROL VOLTAGE SIGNALS. THE TIME CONSTANTS PRODUCED BY THE CIRCUIT ARE CONTINUOUSLY VARIABLE AND RESPOND TO BOTH THE SPEED OF CHANGE AS WELL AS THE EXTENSION OF THE INFORMATION SIGNALS ABOUT THE DIRECTION, SO THAT AS THE DIFFERENCE BETWEEN THE SIGNALS AND SIGNALS OF STEERING INFORMATION, THE VALUE OF TIME CONSTANTS DECREASES TO ALLOW CONTROL VOLTAGE SIGNALS TO FOLLOW CLOSE TO DIRECTIONAL INFORMATION SIGNALS AND AS THE DIFFERENCE BETWEEN CONTROL VOLTAGE SIGNALS AND SIGNALS DECREASES OF INFORMATION ON THE STEERING, THE VALUE OF THE TIME CONSTANTS INCREASES SO THAT THE VARIATIONS IN THE CONTROL VOLTAGE SIGNALS ARE SMOOTH.
