Приймальний тракт гідроакустичного доплерівського лага з автоматичним регулюванням підсилення

Abstract

The proposed receiver of a hydroacoustical Doppler log with automatic gain control contains a preamplifier, a unit for automatic gain control, a signal mixer, a narrow-band filter, and an output amplifier. The first input of the preamplifier is connected to the receiving antenna, the first output is connected to the input of the mixer, and the second output is connected to the input of the unit for automatic gain control. The output of the unit for automatic gain control is connected to the second input of the preamplifier. The input of the output amplifier is connected to the output of the preamplifier via the filter.
