FIELD: radio communications. ^ SUBSTANCE: pulse noise is detected upon conversion of signal received into intermediate frequency, noise active time is determined, information signal is disconnected from amplifier incorporated in superheterodyne receiver, noise-affected part of information signal is recovered by eliminating simulator signals during extrapolation, and superheterodyne receiver is checked for serviceability at intermediate frequency. ^ EFFECT: enhanced precision of superheterodyne receiver serviceability check. ^ 1 cl, 1 dwg |
