Abstract :
A procedure for the fast measurement of the attenuation and delay of data channels in the frequency band of interest (100 to 3400 Hz) is described. The method is based upon the analysis of the steady-state response to a special periodic input sequence; that sequence is pseudo-random and such that the Discrete FOURIER Transform of one period has strict constant amplitude; moreover its length can be chosen equal to a power of 2, in order to facilitate the computation of the D.F.T. by a F.F.T. algorithm. The complete procedure is described; it has been simulated on a computer and the influence of various parameters is reported.
