Title
(EN) DEVICE FOR CALCULATING AN ANALOG FOURIER TRANSFORM
(FR) DISPOSITIF DE CALCUL D'UNE TRANSFORMEE DE FOURIER ANALOGIQUE
Abstract
(EN)
The device transforms an analog input signal with N components x(0), x(1)... x(N-1) into an output signal with N components X(0), X(1)... X(N-1) functions of said components x(0), x(1)... x(N-1), said device comprising basic addition and/or subtraction cells linked in a butterfly-type architecture to perform said functions, each basic cell comprising an operator performing a conditional division by two of the result of the addition (31) operation or subtraction operation performed, the condition being the saturation (33) of said operator.
(FR)
Le dispositif transformant un signal d'entrée analogique à N composantes x(0), x(1)... x(N-1) en un signal de sortie à N composantes X(0), X(1)... X(N-1) fonctions desdites composantes x(0), x(1)... x(N-1), ledit dispositif comportant des cellules élémentaires d'addition et/ou de soustraction chaînées selon une architecture de type papillon pour réaliser lesdites fonctions, chaque cellule élémentaire comporte un opérateur réalisant une division par deux conditionnelle du résultat de l'opération d'addition (31) ou de soustraction effectué, la condition étant la saturation (33) dudit opérateur.
