Abstract
Disposición de conexión para la generación de un valor de regulación, para regular la medida de transmisión de miembros amplificadores o amortiguadores, electrónicamente regulables, en dependencia de una función constante, diferenciable, especialmente para una disoaciación para la compresión y/o expansión de dinámica automáticas, caracterizada porque un miembro de transmisión determinante de la característica de regulación, contiene por lo menos dos transistores, cuyas bases están aplicadas a diferentes tensino-es de referencia y cuyos caminos de corriente de emisor-colector contienen diferentes resistencias en serie, estando unida una entrada del miembro de transmisión con un punto de enlace de los caminos de corriente vecino a los emisores respectivamente colectores de los transistores y una salida está unida con un punto de enlace de los caminos de corriente, vecino a los colectores, respectivamente emisores de los transistores.
