Designing Gaussian Filters in the Structure of a Hydroacoustic Channel

Abstract

The article deals with the modeling and synthesis of Gaussian filters designed for selection of complex noise-like signals in the path of a hydroacoustic receiving station. The formulation and solution of the problem of synthesizing a digital Gaussian IIR filter using methods of discrete nonlinear mathematical programming is presented. An example of solving the problem of discrete synthesis of a 12-bit narrowband Gaussian filter using sampling with a frequency margin is considered. A comparison of its theoretical and experimental characteristics is given.
