Abstract

La presente aplicacion se relaciona con un dispositivo y método para un procesador de valor digital para estimar el cuadro de un valor digital, undispositivo de estimacion de potencia media de senal y un método de procesamiento de valor digital paradeterminar así un estimado del cuadrado de dicho valordigital. Esto se efectua por la aproximacion lineal de la funcion cuadrática con la ayuda de puntos de anclaje que son potencias de 2, de manera tal que elestimado del cuadrado de un valordigital xa es determinado sobre la base de un primer valor de procesamiento 2i, donde 2i < o = xa < 2i + 1, y un segundovalor de procesamiento (3xa - 2i + 1). La presente es ventajosa en que permite pasos de procesamiento simples y un dispositivoelectronic o (hardware) simple deprocesamientos. Es preferentemente aplicado a la estimacion de media de potencia de senal de una senal digital que es enviada a un transmisor.
