During the contract period reported here, the author has investigated the optimal filter as a predictor of area functions of acoustical cavities. A model is presented which predicts spectra of circular cylindrical cavities with uniform steps in the area function. The model is used to fit data derived from the measured impulse response of such cavities. The filter is found to be in error by a length factor in predicting the area function of the cavities. The accuracy of the technique is also sensitive to the spectral content of the signal near the Nyquist frequency.
