【 摘 要 】

The interference effect of impulse noise on the noise immunity of underground communication systems is investigated. A comparative analysis of the noise immunity of an optimal demodulator of the discrete FM signals and of the system "wide band - limiter - narrow band", in the presence of impulse noise, has been carried out.
