Abstract : A computational technique is presented for identifying the impulse response of a linear system from normal operating noisy data. No assumption, however, is made regarding the nature of the noise. The technique derives its idea from the Delay Line Synthesizer (DLS) though in this case the DLS coefficients which discretely represent the weighing function are computed automatically employing the steepest descent method. The method has been tried out on a first order as well as a second order system simulated on a digital computer and the estimated impulse response is found to be very close to the actual one.
