Abstract :
In this paper a blind deconvolution method is proposed which allows the deconvolution of broad-band signals that pass through a low-pass device by combining homomorphic deconvolution and Van Cittert iterative deconvolution techniques. The method has been successfully applied on both synthetic and experimental data obtained from chromatography and deep level transient spectroscopy (DLTS)
