Abstract

Perfeccionamientos en circuitos de señales analógicas y digitales del tipo de circuito de elaboración de señal para desarrollar una señal de salida que es una función compleja de dos señales de entradas variables, que comprenden; un dispositivo de función de transferencia programable para recibir una señal de entrada y producir una señal de salida que mantiene una relación predeterminada elegible con la señal de entrada; medios acoplados al dispositivo de función de transferencia programable para suministrar una primera señal de entrada al dispositivo de función de transferencia mientras elige una primera relación de transferencia para el mismo; caracterizados porque se disponen un primer dispositivo de almacenamiento acoplado al dispositivo de control de transferencia para almacenar una cantidad relacionada con la salida del dispositivo de función de transferencia producida en respuesta a la primera señal de entrada, comprendiendo los medios de suministro y selección una circuitería para suministrar una segunda señal de entrada al dispositivo de transferencia, después de la primera señal de entrada, pero eligiendo una segunda relación para el dispositivo de función de transferencia; y medios acoplados al dispositivo de almacenamiento para multiplicar la señal de salida del dispositivo de función de transferencia producida en respuesta a la segunda señal de entrada por un factor relacionado con la cantidad almacenada para producir una señal de salida compleja, por lo que un único dispositivo de función de transferencia programable puede elaborar en secuencia dos señales de entrada variables y desarrollar una señal de salida compleja que es una función de producto de ambas señales de entrada.
