In the process of detecting and recognizing a digital radio signal, a topical issue is increasing noise immunity. The features of the use of low frequency filters with quadratic and linear response dependence on the input signal are investigated in the article. It is shown that the principle of operation of filters is that the summation process is performed. In this case, the useful signal is summed up coherently and the interference signal is incoherent, ie, the useful signal increases and the interference signal decreases. The filtration process is simulated at different correlation coefficients. This confirmed the possibility of isolating the signal of the means of silent receiving of information by the method of determining the two-dimensional density of the likelihood of interference signal against the background of the common signal. It is proved that the use in the process of signal processing of narrow-banded filters of low frequency allows to increase the noise immunity of the system of detection and recognition of digital radio air signals by 23 %.
