Other AbstractFor the problems of the small signal which travels from the distance and the limited power of acoustic receiver underwater,a kind of design for acoustic general amplifier is presented with low power consumption,high gain amplification and low sensitivity to the errors of passive elements.The electro-circuit system is made up of preamplifier and band-pass filter which comprises four operational amplifiers in series instead of RC low-pass net.This design is applied to possess capabilities that the high gain amplification of small signal and pre-whitening process of sea noise background.The computation of poles of the transfer function shows that the designed amplifier is stable.Sea test proves that the system has merits of high precision,good adaptability,stable performance and low power consumption.
