%X The generation and hanslnission proals of hansmittal sound signals (TSS) is analtysedand a mathematical model of TSS is established in this paper. The power cepsuslcharacteristics of TSS are studied based on the mathematical model and a new analysis method of acoustic txansmission of respilatory syStem using homomorphic processing technique isproposed. The experimental results show that the nounal respiratory system has only onefonnant, while the abnonnal respiratory syStem parenting lung consolidation has twofonnants which the second one plays an boortant role in that systhe. the new method is a simple and an effective one.
